40 Pack 1/4" x 2-1/2" Torx Head Self-Tapping Trailer Deck Screws for Treated Wood (TFX250ACQ-LOTOF40)
Part Number: TFX250ACQ-LOTOF40
This 40-pack of 1/4" x 2-1/2" Torx head self-tapping trailer deck screws is designed for fastening trailer decking to steel structure. These screws are plated for use with treated wood, including newer ACQ-treated lumber, and are intended to cut their own threads into steel with a 7/32" pilot hole.
R&P Knowledge Hub
Compatibility: Fits 1/4" x 2-1/2" trailer deck screw applications requiring a Torx drive fastener for wood-to-steel attachment.
Vehicle / System Fit: Commonly used on utility, equipment, landscape, and other trailers with wood decking fastened to steel crossmembers or frame structure.
Installation Notes: Use a 7/32" drill bit for the pilot hole and a T-30 Torx bit for installation. These screws are designed to cut threads into up to 1/4" thick steel and may also be used with standard 1/4-20 nuts where required.
Performance Insight: The self-tapping design reduces extra hardware steps in many deck-fastening jobs, while the Torx head provides more positive bit engagement than a standard slotted or Phillips head during installation.
R&P Service Insight
Trailer deck screws are often replaced during deck board service, trailer restoration, or when existing fasteners show corrosion, stripped heads, loosening, or reduced holding strength from repeated load and vibration.
-
Wear: Repeated trailer flex, cargo movement, and vibration can loosen or fatigue deck fasteners over time
-
Exposure: Moisture, road salt, and treated lumber chemicals can accelerate corrosion on lower-grade screws
-
Load Stress: Frequent loading, unloading, and deck movement can distort or damage old fasteners during removal and replacement
