Description
Monster Overview:
Tap crisp 5/16-18 threads straight into mild steel, stainless sheet, or aluminum channel with Unslotted Indented Hex-Washer-Head Thread-Cutting Screws, Type 23, Bright Zinc-Bake. The robust ½″ across-flats hex head delivers maximum torque via any nut-driver or impact socket, while a Type 23 triangular chip-relief pocket ejects swarf as it taps—reducing drive torque and leaving clean internal threads.
A broad, non-serrated washer flange spreads clamp load evenly without marring painted or plated surfaces. Bright zinc plating followed by a hydrogen-relief bake supplies dependable corrosion protection and meets RoHS rules. Screws are fully threaded; simply choose the length you need from the drop-down above.
Monster Features:
- High-Torque Drive: Unslotted ½″ A/F hex installs fast and resists cam-out.
- Integrated Washer Flange: Wide bearing surface distributes load—no separate washer needed.
- Type 23 Cutting Point: Large triangular pocket clears chips for smoother cutting & lower drive torque.
- Bright Zinc-Bake Finish: Shiny zinc coat with post-plate bake relieves hydrogen embrittlement—fully RoHS compliant.
- Monster Quality: Tight tolerances, batch inspection, and rapid U.S. shipping.
