Monster Overview:
For marine, food-grade or outdoor steel decking, heavy timbers and trailer floors, reach for 5/16″-18 6-Lobe (Torx) Pan-Head Thread-Cutting Screws machined from rust-proof 18-8 (304) stainless steel. The Type F fluted cutting point taps its own female threads in mild steel or dense hardwood—no nuts, pre-drilling or chip cleanup. Passivated stainless plus a factory dry-wax film deliver top-tier corrosion defence and consistently low drive torque. Supplied in bulk master cartons to keep your per-piece cost monster-low.
Monster Features:
- Type F Cutting Point: UNC machine thread with fluted slot—ideal for 0.060 – 0.200″ steel plate or hardwood planks.
- Drive: Torx® T40 recess — huge torque transfer with virtually zero cam-out.
- Pan Head + Nibs: Wide bearing surface locks decking tight; under-head nibs bite for a flush, skid-proof seat.
- Material Advantage: 18-8 stainless is non-magnetic, food-safe and built for coastal or chemical environments.
- Bulk Packaging: Sealed master cartons—perfect for dock builders, trailer shops & stainless fabrication lines.
