Description
Monster Overview:
Speed through plastic and composite assemblies with #8-18 Slotted Indented Hex Washer Head Type 25 Thread-Cutting Screws from Monster Bolts. The Type 25 point carves its own deep, coarse threads in drilled holes—reducing drive torque and preventing stress cracks. Need flexibility? Drive them fast with a standard 1/4" socket or wrench for maximum torque, or use the straight slot when space is tight.
Every screw receives a zinc coating followed by a bake treatment to relieve hydrogen embrittlement, giving durable indoor corrosion protection while remaining fully RoHS compliant. Orders ship quickly 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 straight slot for flat-blade drivers.
- Integrated Washer: Spreads load and protects the work surface—no separate washer required.
- Zinc-Bake Finish: Zinc plating plus bake treatment for embrittlement relief and long-term durability.
- Low Drive Torque: Self-threading action eases installation and extends tool life.
