Hello, everybody. This is Jeff at etrailer.com. 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.
I placed the order over the phone, was expecting a delivery about midweek of the following week, but it arrived over the weekend. This cut my project time down by four days. Thanks etrailer, keep up the good work!
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.
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.
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.
Worked as expected. Good solid quality. I did drill a small pilot hole in my trailer first to assist the speed of installation.
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 etrailer.com!!
Made it quick and easy to install ground wire securely and properly without getting out too many tool.
Excellent product and fast service. Definitely will buy from them again for all my trailer needs.
Perfect for grounding ring terminals to my trailer.

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.
