Description
Monster Overview:
Designed for trailer frames, dock plates, heavy-gauge sheet-metal and hardwood-to-steel joins, these 5/16″-18 Indented-Hex Thread-Cutting Screws put bolt-level clamp force on tap—no backing nut required. The external hex drive takes sockets or impact drivers for fast, high-torque installation. Each heat-treated carbon-steel blank is finished in brilliant bright-zinc, hydrogen-relief baked to IFI spec, then coated with a factory dry-wax film for smooth, repeatable seating torque. A Type F fluted point taps clean internal threads in a pre-drilled or punched hole; chips clear through the flute—no chip clean-up.
Monster Features:
- High-Torque Drive: Unslotted 5/16″ indented-hex head (½″ wrench size) resists strip-out and accepts power tools.
- Type F Cutting Point: UNC machine thread with fluted slot—forms threads in 0.060–0.200″ steel plate or dense hardwood; chips exit cleanly.
- Bright-Zinc Finish: RoHS-compliant plating, hydrogen-relief baked, topped with factory dry-wax for consistent clamp load.
- Material: Heat-treated carbon steel delivers outstanding tensile & shear strength.
- Bulk Packaging: Sealed master cartons—ideal for trailer builders, dock manufacturers & structural-steel shops.
