Description

Monster Overview:
Lock down sheet-metal cabinets, HVAC panels, electrical boxes and dense hardwood trim with #10-24 × ⅜″ Unslotted Indent Hex-Washer Serrated Thread-Cutting Screws. Heat-treated carbon steel sports a brilliant bright-zinc electro-plate, is hydrogen-relief baked, then factory dry-waxed for reliably low seating torque. A ring of radial serrations under the captive washer bites into steel or wood to resist loosening, while the Type F fluted point taps clean female threads in a pre-drilled or punched hole—chips clear through the flute, no nut needed.
Monster Features:
- Serrated Bearing Face: 360° teeth grab the mating surface, blocking vibration-induced back-out.
- Head / Drive: Unslotted indent hex-washer (5⁄16″ A/F) — smooth top forge; captive washer spreads load.
- Type F Cutting Point: UN C thread with fluted slot — cuts internal threads in 0.060–0.180″ steel or dense hardwood.
- Finish: Bright-zinc (RoHS) + light oil, baked, topped with factory dry-wax for repeatable clamp load.
- Material: Heat-treated carbon steel for high tensile & shear strength.
- Bulk Packaging: Sealed master cartons — ideal for appliance lines, HVAC shops & OEM steel fabrication.
