Description

Monster Overview:
These 5/16″-18 6-Lobe (Torx) Pan Head Screws tap their own mating threads thanks to a Type F fluted cutting point—taps mating threads in a pre-drilled or punched hole—no nut required; chips clear through the flute. Bright zinc electro-plating supplies corrosion protection; every lot is hydrogen-relief baked and factory dry-waxed for ultra-low, repeatable drive torque. Shipped in bulk master cartons to keep your per-piece cost monster-low.
Monster Features:
- Type F Cutting Point: Machine-screw thread with fluted slot—ideal for 0.060-0.200″ steel sheet or dense hardwood.
- Drive: Torx® T40 recess — high torque, virtually zero cam-out.
- Pan Head + Nibs: Wide bearing surface clamps panels tight; under-head nibs bite for a flush, slip-free seat.
- Finish: Bright-zinc (RoHS) + oil, baked for hydrogen relief, topped with factory dry-wax for consistent clamp load.
- Bulk Packaging: Sealed master cartons—perfect for OEM fabricators, trailer builders and fleet maintenance.
