Description
Monster Overview:
Fix your project right the first time with 1/4-14 Slotted Indented Hex Washer Head Type 25 Thread-Cutting Screws from Monster Bolts. These rugged fasteners carve their own deep, coarse threads in drilled holes—reducing drive torque and preventing stress cracks in soft plastics, composites, and thin metals. The combo head design gives you options: drive them fast with a 7/16" socket or wrench for maximum torque, or use the straight slot when access is tight.
Every screw is zinc-plated then bake-treated to relieve hydrogen embrittlement, providing reliable indoor corrosion protection while remaining fully RoHS compliant. Orders ship fast from our U.S. warehouse and are backed by industry-leading support.
Monster Features:
- Type 25 Point: Cuts clean, gripping threads without cracking or splitting plastic.
- Slotted Indented Hex Washer Head: Large bearing surface, high-torque hex drive, plus a slot for flat screwdrivers.
- Integrated Washer: Spreads load and protects the work surface—no separate washer needed.
- Zinc-Bake Finish: Zinc coating plus bake treatment for embrittlement relief and long-term durability.
- Low Drive Torque: Self-threading action eases installation and extends tool life.
