Question:

I have a similar screw used on the plywood bed of my Floe snowmobile trailer. The screw I have is 1 1/4inch from the bottom of the head to the end of the drill tip. Question#1: Does your screw length include the drill tip in the overall length? Is the thread length 3/4inch plus the drill tip, 1/4inch for a total of 1inch length?? Question #2: is this type of a screw available in a longer length? Ive looked at your other screws for deck attachment and they dont appear to have the same size head as this screw.

Expert Reply:

The 1" Long Black Torx Wall Liner Screw part # WLS100 is measured from the head to the tip, so it is 1" long from the highest point to the lowest point. It uses a T25 bit like part # TX425.

We do have the Long Black Torx Wall Liner Screws available in 1-1/2" long part # TFX150, 2-1/4" long part # TFX225, and 2-1/2" long part # TFX250 but these use a T30 bit like part # TX430-1.
