Description
Monster Overview:
Built for marine hardware, food-grade machinery and outdoor steel framing, these 1/4″-20 Phillips Flat-Head Thread-Cutting Screws are machined from corrosion-proof 18-8 (304) stainless steel. The 82° countersunk head seats flush, while a factory dry-wax lubricant keeps drive torque low and predictable. The Type F fluted point taps clean internal threads in a pre-drilled or punched hole; chips clear through the flute—no nut required.
Monster Features:
- Flush Seating & Drive: 82° flat countersunk head with Phillips #3 recess—high torque, tool-friendly.
- Type F Cutting Point: UNC thread with fluted slot—forms threads in 0.050–0.200″ steel plate or dense hardwood; chip ejection built-in.
- Material Advantage: 18-8 stainless is food-safe, non-magnetic (annealed) and resists coastal & chemical corrosion.
- Finish / Lube: Passivated surface + factory dry-wax (silicone-free) for consistent clamp load.
- Bulk Packaging: Sealed master cartons—ideal for dock builders, trailer shops & stainless fabrication lines.
