Description
Monster Overview:
Fix your project right the first time with 5/16-18 Unslotted Indented Hex Washer Head Thread-Cutting Screws, Type 1, Zinc-Bake Finish from Monster Bolts. These heavy-duty fasteners feature a single cutting edge and tapered machine-screw threads that carve clean internal threads in structural steel, thick sheet metal, and other ductile materials. The integrated washer head spreads load without a separate washer, and the unslotted design installs quickly with a standard ½″ hex socket or wrench—no screwdriver slot to strip or fill with debris.
A bright zinc-bake coating delivers reliable corrosion resistance and meets RoHS requirements. Count on Monster Bolts for premium quality, fast U.S. shipping, and industry-leading customer support.

- Integrated Washer Head: Distributes clamp load—no separate washer needed.
- Type 1 Cutting Point: Single cutting edge and blunt point form precise threads with low drive torque.
