Description
Monster Overview:
Tackle steel framing, trailer decks, dock builds and hardwood-to-steel assemblies with #12-24 Unslotted Indent Hex-Washer Head Thread-Cutting Screws. Heat-treated carbon-steel fasteners get a lustrous bright-zinc electro-plate, are hydrogen-relief baked to IFI specs, then factory dry-waxed for consistently low drive torque. The captive washer flange spreads load, while the Type F fluted point taps mating threads in a pre-drilled or punched hole—chips clear through the flute, and no nut is required.
Monster Features:
- Head / Drive: One-piece unslotted indent hex-washer (5⁄16″ AF) — smooth top forge; captive washer locks onto steel or wood.
- Type F Cutting Point: UNC machine thread with fluted slot — creates clean internal threads in 0.060–0.200″ steel plate or dense hardwood.
- Finish: Bright-zinc (RoHS) + light oil, hydrogen-relief baked, topped with factory dry-wax for repeatable clamp load.
- Material: Heat-treated carbon steel for high shear and tensile strength.
- Bulk Packaging: Sealed master cartons — ideal for OEM steel fabrication, trailer shops & dock builders.
