Description
Monster Overview:
Build it once—build it right—with #8-18 Slotted Indented Hex Washer Head Type 25 Thread-Cutting Screws from Monster Bolts. Precision-machined from 18-8 stainless steel, these fasteners cut their own deep, coarse threads in drilled holes—reducing drive torque and eliminating stress cracks in soft plastics, composites, and thin metals. Zip them in with a standard 1/4" socket or wrench for maximum torque, or use the straight slot when clearance is tight.
Stainless construction means no plating to chip or peel and inherent RoHS compliance. Every order ships fast from our U.S. warehouse and is backed by industry-leading support.
Monster Features:
- Type 25 Point: Cuts clean, gripping threads without splitting plastic.
- Slotted Indented Hex Washer Head: Large bearing surface, high-torque hex drive, plus a straight slot for screwdriver access.
- Integrated Washer: Spreads load and protects the work surface—no separate washer required.
- 18-8 Stainless Steel: Excellent corrosion resistance—ideal for outdoor and harsh environments.
- Low Drive Torque: Self-threading action eases installation and extends tool life.
