Description
Monster Overview:
One screw, two drive options, zero backing nuts. #12-24 Slotted Hex-Washer Thread-Cutting Screws combine an indented hex head + broad slot for socket-gun speed and screwdriver access in tight spots. The integral washer spreads load and seals oversized holes, making them ideal for trailer skins, HVAC cabinets, appliance panels, dock plates and hardwood-to-steel assemblies. Heat-treated carbon steel is finished in brilliant bright-zinc plating, hydrogen-relief baked to IFI spec, then factory dry-waxed for smooth, repeatable seating torque. A Type F fluted point taps clean internal threads in a pre-drilled or punched hole; chips exit through the flute—no weld, no chip clean-up.
Monster Features:
- Dual-Drive Convenience: Indented #12 hex head (5/16″ wrench) plus wide slot—socket, impact gun or flat driver.
- Integrated Washer: Enlarged bearing surface resists pull-through and helps seal joints in sheet-metal.
- 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, factory dry-waxed for consistent clamp load.
- Material: Heat-treated carbon steel delivers excellent tensile & shear strength.
- Bulk Packaging: Factory-sealed cartons—ideal for OEM fabrication, trailer shops & structural-steel installers.
