The Type F machine-screw point cuts its own threads\ninto drilled steel crossmembers up to 1\/4\" thick - drill a 7\/32\" pilot in the\nsteel (Type F chart max 1\/0.228\"), drive through the deck board with an\nimpact driver, and the screw pulls the board tight to the frame with a\nmachine-thread connection. This length suits 2\" nominal decking. Unlike lag\nscrews or drill-point screws, the tapped threads survive board replacement:\nremove the screw, replace the board, re-drive. The countersunk head with\ncutting nibs seats flush in hardwood and softwood decking. Use on utility\ntrailers, equipment and flatbed trailers, dump beds, truck bodies and any\nwood-over-steel floor.
