Bulk 1/4"-20 Slotted Indented Hex Washer Thread Cutting Screw Type 23 – Full Thread Zinc-Bake

Monster Overview:

Tap clean threads and clamp securely with 1/4-20 Slotted Indented Hex-Washer-Head Thread-Cutting Screws, Type 23, Bright Zinc-Bake. The dual-drive head pairs a robust 7/16″ across-flats hex for high-torque installs with a full-width straight slot for screwdriver access when sockets can’t reach. A Type 23 triangular chip-relief pocket at the point ejects swarf while cutting—reducing drive torque and leaving crisp internal threads in mild steel, stainless sheet, or aluminum channel.

The wide, non-serrated washer flange spreads clamp load without scratching painted or plated surfaces. Bright zinc plating followed by a hydrogen-relief bake supplies dependable corrosion protection and full RoHS compliance. Screws are fully threaded; simply choose your required length from the drop-down above.
