Festive Deal Bulk #10-24 × ⅜″ Unslotted Indent Serrated Hex-washer Head Thread-cutting Screws — Type F, Bright Zinc Collection [x6K1oFqV]

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.

• Material: Heat-treated carbon steel for high tensile & shear strength.
