Monster Overview:
Fix your project right the first time with #8-18 Phillips Flat-Head Type 25 Thread-Cutting Screws from Monster Bolts. These screws cut their own deep, coarse threads in drilled holes—so they drive with less torque and put minimal stress on soft plastics and composites. The 82° countersunk head seats perfectly flush, leaving a clean, snag-free surface ideal for panels, covers, and trim pieces.
Each screw is zinc-plated then bake-treated to relieve hydrogen embrittlement, providing dependable 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.
- Flat (Countersunk) Head: 82° profile seats flush for a professional, snag-free finish.
- Phillips Drive: Cross-recessed head pairs with standard #2 Phillips bits for reliable torque transfer.
- Zinc-Bake Finish: Zinc coating with post-bake treatment for embrittlement relief and long-term durability.
- Low Drive Torque: Self-threading action eases installation and extends bit life.
