What Drill Bit Should be Used for the 2-1/2" Long Torx Screw # TFX250ACQ

Question:

Hi, I am in the process of replacing my trailer boards with pressure treated lumber. I am planning to purchase your 2 1/2 inch Torx screws to secure the new boards. Questions I have are: 1 should I use the same holes in the trailer frame or drill new ones? 2 What type of drill bit should I use to drill the 7/32 inch pilot holes, i.e cobalt? 3 What size Torx bit does your bolt need? T30/T40? Thanks!

I would go ahead and use the same holes that are already on your trailer. just make sure that they are the 7/32" diameter needed for the 2-1/2" Long Torx Screw # TFX250ACQ.

When it comes to what type of drill bit we don't really have a recommendation. Since every application is different it is really up to the customer's discretion.

The Torx Head Screwdriver Bit # TX430-1 is what fits this screw. It has the standard 1/4" hex driver bit on one end and then a TRX 30 bit size for the screw.

This screw comes in a quantity of one so you just need to change the quantity to how many you are needing. Might be useful to order a few extra just in case.
