Video Transcript for Redline Accessories and Parts TFX225ACQ Review

Today, we're going to review the two and a quarter inch long Torx trailer floor and wall liner screw for the ACQ treated wood. These Torx flathead screws make securing a wood floor to your trailer very quick and easy and economical. This screw, in particular, has the type F point, which is designed for securing your wood floor that have the gauge sheet metal. This screw is also specifically designed for use on the ACQ wood, which is Alkaline Copper Quaternary wood. Now, because this ACQ treated wood is very corrosive, these screws have been made with an approved plating material that is less expensive than using stainless steel screws and has been shown to outperform the galvanized screws. If you noticed it has the tapered flathead, which will sit flush with the surface after they're installed. Few specs on this, the size Torx on this is T30.

The diameter of this is one quarter inch in diameter. The length, I'm going to measure for you, is going to be right at two and a quarter inches long. We have mentioned it has the type F point, which is a blunt tip, but if you see as I rotate, it has multiple cutting surfaces. When you do install this, you do need to require or it does require drilling a pilot hole of 7/32 to install these. That should do it for the review of the two and a quarter inch long Torx trailer floor and wall liner screw for the ACQ treated wood.

by: John S02/10/2015

Worked great! Drilled in 200 of these screws and only 1 broke. The one that broke was justified as I was going through 2 layers of 10ga steel on that one spot. The second one I tried went in fine. Shipped fast and worked as promised. My recommendations to use this easily: Drill 7/32" pilot holes with a cobalt bit and have a lot of bits on hand if you plan to drill a lot of holes. Also, use a T30 screw bit and if you have one, an impact driver is recommended. Boards are now sitting secured and tight to the frame. Very pleased and much easier than carriage bolts. 173138


After 1 year, all the screws are still holding strong and none have backed out, corroded, or broke. Still very Happy!

All of the screws went in without bending, stripping or braking. I redecked a utility trailer with 2x8's. The frame cross-braces were 3/16 angle steel. I highly recommend getting a few cobalt 7/32 drill bits, either pilot point or split point. Don't try to use regular drill bits for the pilot holes. Even the cobalt bits will dull if you don't use cutting oil between holes (I used bar oil). Also, try to place your pilot holes where there is only one layer of metal. I broke a bit in one of those spots that is now a permanent part of my trailer. Other than that, just make sure you use a good quality T30 bit and an impact driver. Great product. 125448

Great service for Trailer parts. The deck screws arrived in perfect condition. Price couldn't be beat, hard to find part. Perfect for re-decking my home built trailer. I'll shop your store again... Thx 68773

Screws worked very good for fastening new 2x8 PT boards on my flatbed trailer. Did have a few break but quickly found a little trick that worked great. After pilot drilling the holes shoot a squirt of white lithium grease down the hole in the board and screws go in like butter using a 1/2" drive impact wrench. Also make sure you have plenty of drill bits, I went through 4 to sink 165 screws. 267830


by: Roger H.09/08/2016

The delivery was super fast. The product worked flawlessly with no failures out of 86 screws. I was surprised how easy and fast the project went. It was the first time I purchased from etrailer and came away after my purchase and viewing their website that they are people that really care about the customer and also their employees. I will be purchasing more items from them. 292286

by: David10/22/2012

These screws seem to be well made and the coating should help them last a long time. They are much better than the rusted ones that came with the trailer (only 2 years old). Installed with an impact wrench and none snapped. 57806


by: Charles01/20/2012

Use the size drill bit they tell you to use and they go right in. Try one size to small and they will snap off. I have not hauled anything with the trailer since I redecked it but do not foresee any problems 30048


by: Sam G.09/08/2016

Do you have a question about this Accessories and Part?

  • Recommendation For Screws To Attach Pressure Treated Decking To a Flat Trailer
  • I would recommend to use the treated torx screws for ACQ (Alkaline Copper Quaternary) treated wood for better corrosion and rust resistance. The treated torx screws like the Redline 2-1/2 Inch Long Torx Trailer Screw for ACQ Treated Wood, part # TFX250ACQ, are plated with a material that will resist the ACQ preservative used in treated wood, which is very corrosive because of the high levels of copper it contains. When using ACQ timber it is necessary to use double-galvanized or stainless...

  • What Size Hole is the T-Handle Locking Stainless Steel Flush Door Latch # L4080 Designed to Fit
  • The T-Handle Locking Stainless Steel Flush Door Latch # L4080 that you referenced is designed to be installed in a 2-3/4 inch by 3-3/4 inch hole. You will need to cut a hole that size in the door you have where ever you want the latch to be. For wood screws you could use the # TFX225ACQ for a 2-1/4 inch long screw or the part # TFX150 for a shorter screw that is 1-1/2 inches long. I attached a review video for this latch for you to check out as well.
