Type and Size Fastener to Attach ACQ Treated Deck Boards to Aluminum Trailer Frame

Question

Question:

I have an aluminum trailer and would like to attach ACQ treated 3/4inch deck boards to the aluminum tube framed sides. What type/size do you recommend? Self tapping? Thank you very much?

The length of the screw you need will depend on how thick the tubing is. You can use the shorter 1-1/2 inch length # TFX150ACQ, which will get you through the deck boards and into the tubing. The screws we offer are specially designed to work with the ACQ treated wood. If you used anything other than screws rated for ACQ lumber (like the # TFX225 you referred to) or ones made from stainless steel, they chemicals in the wood would cause the hardware to corrode pretty quickly. The screws are 1/4 inch in diameter, for plenty of bite.

The screws aren't self tapping. You'd need to drill a 7/32 inch pilot hole.
