Description
Monster Overview
Skip loose lock-washers and nuts—our #10-24 Slotted Serrated Hex-Washer Thread-Cutting Screws deliver bolt-strength clamping plus mild vibration resistance in one fastener. Serrations under the flange bite into the mating surface to resist loosening, while the built-in washer spreads load on thin sheet or plate. Heat-treated carbon steel wears a brilliant bright-zinc finish, hydrogen-relief baked to IFI spec, and factory dry-waxed for smooth, repeatable seating torque.
Monster Features
- Serrated Flange Head — Teeth grip the work surface for mild vibration resistance; wide flange eliminates the need for a separate washer.
- Dual-Drive Convenience — Indented #10 hex (¼″ wrench) plus broad slot—install with a socket, nut-runner or flat driver.
- Type F Cutting Point — #10-24 UNC machine thread with fluted slot taps clean threads in 0.060–0.180″ steel plate or dense hardwood; chips exit through the flute.
- Bright-Zinc Finish — RoHS-compliant plating, hydrogen-relief baked, factory dry-waxed for corrosion protection and consistent clamp load.
- Material — Heat-treated carbon steel provides excellent tensile & shear strength.
- Bulk Packaging — Factory-sealed master cartons—perfect for trailer fabrication, dock builders & metal-shop production lines.
