Monster Overview:
Fix your project right the first time with 1/4-20 Slotted Indented Hex Washer Head Thread-Cutting Screws, Type 1, Zinc-Bake Finish from Monster Bolts. A single cutting edge and tapered machine-screw threads create clean internal threads in sheet metal, channel, and other ductile materials. The integrated washer head distributes load while the slotted indent lets you drive with either a 3/8″ socket or a flat-blade screwdriver.
A bright zinc-bake coating provides dependable corrosion protection and meets RoHS requirements. Count on Monster Bolts for premium quality, fast U.S. shipping, and industry-leading customer support.
