Description
Monster Overview:
Built for truck beds, dock plates, heavy-gauge steel framing and hardwood-to-steel assemblies, these 1/2″-13 Slotted Hex-Washer Thread-Cutting Screws put serious clamp force on tap—no backing nut needed. The indented hex head + screw-driver slot gives installers two drive options, while the integral formed washer spreads load to resist pull-through and seals oversized holes. Heat-treated carbon steel receives a brilliant bright-zinc plating, is hydrogen-relief baked to IFI specs, and finished 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 exit through the flute—no chip clean-up, no welding, no nut.
Monster Features:
- Dual-Drive Convenience: Indented 1/2″ hex head (3/4″ wrench) with slot—use a socket, impact gun, or large flat screwdriver in tight spots.
- Integrated Washer: Enlarged bearing surface safeguards thin or slotted sheet and helps seal out moisture.
- Type F Cutting Point: UNC machine thread with fluted slot—forms threads in 0.090–0.250″ 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 supplies exceptional tensile and shear strength.
- Bulk Packaging: Factory-sealed cartons—ideal for trailer manufacturers, dock builders & structural-steel shops.
