Description
Monster Overview:
Built for fastening steel decking, truck beds, trailers and heavy plywood flooring, these 1/4″-20 6-Lobe (Torx) Flat Head Floor-Board Screws use a Type F thread-cutting point that taps its own female threads in mild steel or hardwood—no nuts, no pre-tapping.
A tough black-phosphate conversion coat with light oil meets RoHS requirements and provides low-glare corrosion protection, while the factory wax/oil film keeps drive torque predictably low. Supplied in bulk master cartons for rock-bottom per-piece cost.
Monster Features:
- Type F Cutting Point: Machine-screw thread with fluted cutting slot—ideal for 0.030-0.200″ steel or dense hardwood.
- Drive: Torx® T25 6-lobe recess—high torque, virtually zero cam-out.
- Floor-Board Flat Head: 82° countersunk profile seats flush; under-head nibs bite for a clean, level set-down.
- Finish: Black phosphate & oil (RoHS) + factory dry-wax for consistent clamp load.
- Bulk Packaging: Sealed master cartons—perfect for OEM metal-fabrication and trailer-floor rebuild shops.
