Product Details
✓Type F Thread-Cutting Design: Type F thread-cutting tip cuts threads into steel cross-members through a 9/32 in. pilot hole - no separate tapping step; oil phosphate coating lubricates on contact to reduce drive effort and extend bit life during high-volume floorboard screw installation; this is not self-drilling
✓Wide Trailer Compatibility: flatbed, drop-deck, curtain-side, dry van, enclosed, utility, gooseneck, and horse/livestock trailers; suitable for apitong, hardwood, and softwood deck boards fastened to steel cross-member and C-channel frames
✓Flush Flathead Profile: sits at or below deck surface - no raised head to snag straps, tarps, or pallet runners during cargo loading and unloading; essential for flatbed and enclosed trailer floor installations
✓Case-Hardened Carbon Steel Construction: Case-hardened carbon steel per SAE J933 - HRC 45 minimum surface hardness, 306 lb-in minimum torsional strength; black phosphate and oil finish for corrosion resistance; fully threaded UNC 5/16-18 right-hand shank for maximum holding strength in wood-to-metal trailer frame connections
✓Six-lobe Torx drive delivers higher torque transfer and lower cam-out rate than hex or Phillips - reduces bit wear and strip-out risk during production trailer floor screw installation
✓Dimensions and Threading Specifications: with UNC 5/16-18 threading (18 threads per inch), right-hand, fully threaded shank provides consistent clamping force and serves as an upgrade from 1/4-20 fasteners for better holding strength for heavier loads
