Description
Monster Overview:
For marine builds, food-grade equipment and outdoor steel decking, choose 5/16″-18 6-Lobe (Torx) Flat-Head Thread-Cutting Screws machined from corrosion-proof 18-8 (304) stainless steel. The 82° countersunk head seats flush, while the Type F fluted point taps clean internal threads in a pre-drilled or punched hole—chips clear through the flute, so no nut is required. Passivation plus a factory dry-wax film keep drive torque low and predictable.
Monster Features:
- Flush Seating: 82° flat head leaves surfaces smooth and snag-free.
- 6-Lobe Drive: Torx® T40 recess—high torque transfer with virtually zero cam-out.
- Type F Cutting Point: UNC thread with fluted slot — taps threads in 0.060 – 0.200″ steel plate or dense hardwood; chips exit cleanly.
- Material Advantage: 18-8 stainless is non-magnetic, food-safe and resists coastal or chemical corrosion.
- Bulk Packaging: Sealed master cartons—ideal for dock builders, trailer shops & stainless fabrication lines.
