Video Transcript for Review of Flint Hill Goods Trailer Wiring - Hex Self Tapping Screw - FA1131822

Hello, everybody. This is Jeff at Today I'm gonna take a look at this 1/4 inch by 14 by 3/4 inch long unslotted hex drive zinc finish self-drilling screw. This is for a quantity of one. Now if you notice, this is an unslotted hex washer head self-drilling screw, has a zinc coating for corrosion resistance, and this is great for use on grounding wires with a 1/4 inch diameter ring terminal. As we mentioned, the size on this is 1/4 inch by 14 by 3/4 inch long threads.

The overall length of this is 3/4 of an inch. The hex head size on this is 3/8 of an inch, and it is a steel construction with zinc-plated finish, and it is case hardened. But that should do it for the review on this 1/4 inch by 14 by 3/4 inch long unslotted hex drive zinc finish self-drilling screw.

Self-Tapping Screw - 1/4" -14 x 3/4" Long - Zinc - FA1131822

Average Customer Rating:  4.9 out of 5 stars   (68 Customer Reviews)


Excellent product and fast service. Definitely will buy from them again for all my trailer needs.


Worked well on my boat trailer for mounting lights on metal frame. If you have never used self tapping metal screws the secret to making the process quick and easy is to drill a pilot hole just slightly smaller in diameter than the screw threads. If your drill bits are not the sharpest in the world another tip is to start with a smaller bit and then use successive larger bits until the hole is slightly smaller than the screw.



After one year of exposure to the elements an being in and out of water at boat ramps, and traveling some fairly rough roads to reach boat ramps, these fasteners are still securely in place.

Exactly what I needed to rewire a 20-year-old trailer that was starting to show it's age with inconsistent lighting performance and continuity issues. In addition to purchasing this lighting harness, I upgraded all my incandescent bulb side markers and taillights with LED units and complete rewired the trailer. etrailer had everything I needed in one place with excellent pricing and superb service. Everything is working great and I love the brightness and visibility of the LED lights.


Did the job of installing new jacks.


Good for what it is, but note that these are too short to go through, say, tie-down racks then plywood sidewalls, and into the metal framing of a utility trailer. The picture does not really show the relative length of the threaded part and the drilling part for this length screw.


I am very happy with the quality of the products and the service! Most of all I want to compliment you on the instructional videos included in your websit. They are simple to follow, informative and answered several questions I had about the products and the installation. I will definitely be back when needed and highly recommend!!


Worked as expected. Good solid quality. I did drill a small pilot hole in my trailer first to assist the speed of installation.


Used 8 of these screws to attach two scissor jacks onto my pop-up frame. These worked just as expected


I was worried that the screws might of been lost as the box the order came in was really beat up. But nope they were there.


installed yesterday easy install great product thanks will be ordering a front receiverfor my 2015 gmc sierra soon thanks


Made it quick and easy to install ground wire securely and properly without getting out too many tool.


Perfect for grounding ring terminals to my trailer.


I first drilled a pilot hole but they worked well.

  • LED Light Kit Availability for a Hollywood Racks Electronic Bike Rack
    We don't have anything custom fit to allow you to install lights on your Hollywood Racks SE E-Bike Rack part # HLY84FR the part # 98174LED is an LED light kit for cargo carriers that would be the best starting point we could offer. You could use the brackets # BK70BB to secure the assemblies to the rack with self tapping screws like part # FA1131822.

  • How To Properly Ground The Wires On Electric Drum Brakes
    Typically the ground wire would be connected to the frame of the trailer using ground screws like # FA1131822 and a ring terminal like part # DW05740-1. Using heat shrink is always recommended to help prevent corrosion. Connecting the ground to the axle technically would work, but the frame will be a much more secure location. You should be able to find a good clean spot on the frame and keep the grounds protected and out of the elements as much as possible.

  • How to Install the Peak Backup Camera Part # PKCOBU7 on a Horse Trailer
    The first step for installing the Peak Backup Camera Part # PKCOBU7 would be to mount the rear-view camera somewhere inside the horse trailer. You can use the Self-Tapping Fasteners for License Plates and License Plate Frames part # CR80430 to install the bracket/camera. Once the camera is in position, you will have two wires to connect. One will be red for the 12-volt power and the other will be black for the ground. Strip about 1/4" of the jacket off of each wire. Once done you will...

  • Hardware Used to Mount Optronics 7-Way Trailer Harness Plug Protector
    You can use whatever hardware works best for you and the location on your trailer that you want to mount the Optronics 7-Way Trailer Harness Plug Protector # ACP7B. When we installed the protector in the linked video, we used Self-Tapping Screws 1/4 Inch # FA1131822.

  • How to Ground a Trailer Light
    I was not able to reference the tow smart light kits you are referring to but a trailer taillight will ground one of two ways. They can either ground using a single wire (usually white) or through the mounting hardware. If they ground using a single wire then that wire will need to be attached to a bare metal part of the trailer frame with a screw like part # FA1131822 and a ring terminal like part # DW05737-1. If there is any paint on the ground location then you will need to sand it down...

  • Does the Kodiak Hydraulic Brake Line Kit Come with Hardware
    The Kodiak Hydraulic Brake Line Kit part # 18SI-BLKIT doesn't come with hardware for the liner holders. The reason for this is that the exact hardware you need will vary by application and preference. In most cases, self-tapping screws will be best but other times you may want to drill and bolt the line in place. If you want to pick up some self-tapping screws with the line kit I recommend the Self-Tapping Screw part # FA1131822.

  • Gauge Steel Used for etrailer Scissor Stabilizer Jacks, Mounting Hardware, and Base Pads
    Thanks for reaching out, Mark! The Scissor Stabilizer Jacks w/ Handle - 18-3/4" Lift - 10,000 lbs # TJSCHD-24-4 are designed with 11 Gauge steel and install using 1/4" self-tapping screws like the Self-Tapping Screw # FA1131822. Then for base pads you just need two kits of the SnapPad SnapJack SJ for RV Scissor Jack Stabilizers # SN65FR and you'll be good to go!

  • Recommended Power Awning for 2016 Winnebago Trend 23L
    For your 2016 Winnebago Trend 23L, the awning that comes with the unit is 15 feet. For a complete power awning I recommend the Solera 12V XL Power RV Awning - 15' Wide - Extra-Long 9'8" Projection - Black Fade # LCV000334950-362243 which is a top of the line option. I've attached a video of the installation to assist. If you want to piece a system together, I recommend the Solera 12V Power RV Awning Conversion Kit - Universal - 69" Arms - Black # LC434723, the Solera Awning Rail Extrusion...

  • Hardware to Install 5/16" Diameter Coupler Pin w/ Chain on Trailer Coupler
    You can use the 1/4" Self-Tapping Screw # FA1131822 to secure the 5/16" Diameter Coupler Pin w/ Chain # 37201181 to your trailer. Just run it through the last link in the chain and be sure to avoid going through any parts of the coupler that have something on the other side that could be damaged.

  • Recommended Light Kit for Curt Hitch Mounted Cargo Carrier
    There is no light kit specifically designed for the Curt Cargo Carrier, part # C18152, but we do have a solution that will work for you. You can use an LED light kit like part # 98174LED. You would then need two brackets, part # BK70BB. To attach the brackets to the carrier you will need self-tapping screws like part # FA1131822 or you can use other hardware to mount the light brackets. This light kit does come with a 4-way trailer connector so if your Acura needs a wiring harness I...

  • Can I Add Lights To Hollywood Racks Sport Rider SE
    The only real way to add lights to the Hollywood Racks Sport Rider SE part # HLY74FR is to add mounting brackets part # BK70BB with the LED light kit part # 98174LED. This light kit plugs into the 4-way that you mention because they are designed to added to cargo carriers. To add the bracket you will need self tapping screws part # FA1131822. This is the only way to add lights besides the magnetic lights you referenced. You do want to keep in mind that drilling into the bike rack with screws...

  • Adding LED Lights To A Hollywood Racks Sport Rider SE 4
    We have definitely seen customers do this and modify racks like the EasyFold # TH903202 before using the LED kit part # 98174LED and the brackets # BK70BB to mount. You will also need some self-tapping screws # FA1131822, or drill and use the hardware of your choice to mount the brackets. Doing modifications on the Sport Rider SE 4 # HR1400Z can cause a voiding of the warranty so that's worth checking out with Hollywood Racks before taking this on. Another option to consider that doesn't...

  • Are 3/8" Self Tapping Screws Available
    Glenn it does not look like we carry any 3/8" self tapping screws. We do have the Self-Tapping Screw # FA1131822 which is 1/4" - 14 x 3/4" or the Hex Screw # 101131802 which is #8 x 1/2" but no 3/8" unfortunately.

  • Cost Effective Wiring To Install 7-Way For Curt Echo Controller on 2008 BMW X5 With Battery in Trunk
    The Curt Trailer Connector Adapter part # C57672 can certainly be used to install a 7-Way on the 2008 BMW X5 to use the Curt Echo Wireless Brake Controller part # C51180 instead of the kit part #ETBC7L. I recommend to use the Curt trailer connector part # C57672 and the Power Wire Kit for Electric Trailer Brake Controllers part # BRK-ELECKIT because it has a shorter amount (10 feet) of 12 gauge wire since your battery is in rear cargo area. This kit also comes with all of the components...

  • How to Wire Triple Tail Light with Separate Stop, Turn and Tail Light Functions
    If what you're trying to do is replace your Grote incandescent tail lights (very similar to the Optronics Jeep-Style Tail Light # ST60RB) with three separate LED lights, or a Triple Tail Light, like # 47-85-002, then connecting the two black wires on the red LED lights is what you want to do for running lights. Most modern LED lights that have a 3-wire pigtail, use the following color functions: Red: Turn signal and brake Black: Tail light White: Ground If you haven't already done so,...

  • How Does Brake Controller Install Harness for a 2013 Toyota Tacoma Ground
    The reason you have to also run a separate ground on the # 3040-P to install the P2 part # 90885 is because the ground of the harness just isn't quite sufficient enough for powering the brake controller. If you watch the install video I attached that shows this harness installing a brake controller in a similar 2012 Tacoma you can see exactly how we grounded this harness. All you need to do is use a self tapping screw with a drill and run the ring terminal to the sheet metal right near...

  • Recommended Trailer Connector and Wiring to Add 7-Way Trailer Connector to 4-Way for Reverse Lights
    For your reverse lights on your boat trailer, I recommend you start with converting the 4-way you have into a 7-way trailer connector. I recommend the Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector # 30717 for this. You will simply plug in your current 4-way and then connect the white wire with the ring terminal to your frame bare metal to metal using # FA1131822. Then you will connect the yellow wire of this adapter to the reverse light power at your tail light on one side of...

  • Parts Needed for Custom Wiring a Trailer For Separate Turn and Brake Lighting
    In order to have separate turn and brake lights on your trailer, I strongly recommend using a 2-wire to 3-wire converter, like the Tow Ready # 118158 on the trailer. This will allow you to have 4-way connectors on both the vehicle and the trailer. The 4-way connectors are much more common than 5-way connectors, and will allow to you tow other things with your vehicle, or tow your trailer with other vehicles, without the need for an adapter. This converter box is not designed to be exposed...

  • Fastener Recommendation to Attach Round Rubber Bumper D3-96
    You could use some self-tapping screws like # FA1131822 to avoid drilling holes first. If you know about where the wiring is you could position the bumper # D3-96 so as to avoid the wiring. Or another option would be to drill from the backside, if possible, so you can avoid the wiring for sure. Or another option would be some type of anchor bolt or screw but that would still require drilling.

  • What to Do w/ the Black and Red Wire When Wiring a 7-Way Connector
    The black wire is usually the 12v power wire that typically goes in the 11 o'clock position on the trailer side 7-way connector as you are looking directly at the front of it. It'll keep your battery charged, run an electric jack, or something along those lines. Not the end of the world if you don't have anything to run it to. Now the red wire is going to do something with your left side trailer lights if you are wiring your 7-way in a standard configuration so it's pretty important. I...

  • Self Tapping Screw Recommendation for Installing Exterior Light on Trailer
    Self tapping screws like the part # WLS100 which has a Torx head or a part # FA1131822 which is a hex head style bolt would work well. We don't normally see people seal the lights to the trailer as most light assemblies are a weather proof or waterproof design and don't require it. For a sealant we recommend the # 0160297 for sealing trailer roof vents. This would work well for a light assembly as well.

  • How Do I Ground The White Wire When Assembling A Malone Kayak Trailer
    It is odd that the Malone instructions for the trailer # MPG464-LB do not mention connecting the ground anywhere. On a trailer like this, the white wire can be grounded on the steel frame (usually near the tongue) using a self tapping screw # FA1131822 and a ring terminal # DW05737-1. Preferably an out of the way location where it is out of the elements. Make sure it is grounded to good clean metal, free of any corrosion. A bad ground would certainly explain the issue with your lights.

  • If Brake Wiring is Damaged do Trailer Brakes Need to be Changed Out
    If it's just the wiring that has been damaged then you only need to replace the brake wires. We recommend using 10 Gauge Wire # 10-1-1 and Heat Shrink Butt Connectors # DW05745-5 for the installation. Electric brake assemblies have 2 wires; 1 for power and 1 for ground. It doesn't matter which wire on the brake assembly is used for which function. Should your ground connections be damaged as well then you can use the Ring Terminal # DW05740-1 for the ground wire and the Self-Tapping Screw...
