Monster Overview:
Fix your project right the first time with #12-14 × 1/2" Unslotted Indented Hex Washer Head Type 25 Thread-Cutting Screws from Monster Bolts. These heavy-duty fasteners carve their own deep, coarse threads in drilled holes—reducing drive torque and minimizing stress on soft plastics, composites, and thin metals. The integrated washer head spreads load, while the indented hex drive delivers high torque with a standard 5/16" socket or wrench.
Zinc plating followed by a bake treatment relieves hydrogen embrittlement and provides dependable indoor corrosion protection, all while remaining fully RoHS compliant. Every screw ships fast from our U.S. warehouse and is backed by industry-leading support.
Monster Features:
- Type 25 Point: Cuts clean, gripping threads without cracking or splitting plastic.
- Indented Hex Washer Head: Large bearing surface & high-torque drive—no slots to strip.
- Integrated Washer: Distributes load and protects material; no extra washer required.
- Zinc-Bake Finish: Zinc coating plus bake treatment for embrittlement relief and durability.
