Description
Monster Overview:
Create strong, flush joints in channel, framing, and sheet with 5/16-18 Slotted Indented Hex-Washer-Head Thread-Cutting Screws, Type 23, Bright Zinc-Bake. The head combines a rugged ½″ across-flats hex for high-torque driving with a full-width straight slot for flat-blade access in tight clearances. A Type 23 triangular chip-relief pocket at the tip ejects swarf while tapping— lowering drive torque and leaving crisp internal threads in steel, stainless sheet, or aluminum.
The wide, non-serrated washer flange spreads clamp load without marring painted or plated surfaces. Bright zinc plating plus a hydrogen-relief bake delivers dependable corrosion protection and full RoHS compliance. Screws are fully threaded; simply choose your required length from the menu above.
Monster Features:
- Dual-Drive Head: ½″ A/F hex and straight slot for maximum installation flexibility.
- 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 torque.
- Bright Zinc-Bake Finish: Shiny zinc coat with post-plate bake to relieve hydrogen embrittlement—RoHS compliant.
- Monster Quality: Tight tolerances, batch inspection, and fast U.S. shipping.
