Description
Monster Overview:
Get a flush, high-strength finish with 1/4-20 Phillips Flat Head Thread-Cutting Screws, Type 23, Zinc-Bake from Monster Bolts. The 82 ° countersunk head seats level with the surface, while a Type 23 triangular chip-relief pocket ejects swarf as it cuts—lowering drive torque and leaving crisp internal threads in steel, aluminum, and other ductile materials.
Bright zinc plating followed by a hydrogen-relief bake provides dependable corrosion protection and full RoHS compliance. Screws are fully threaded—just select your required length from the drop-down above.
Monster Features:
- Flush-Fit Flat Head: 82 ° countersink sits flat for snag-free, professional finishes.
- Type 23 Cutting Point: Large triangular chip pocket ejects chips for smoother cutting & lower drive torque.
- Phillips Drive: #3 Phillips recess delivers secure, cam-out-resistant installation.
- Zinc-Bake Finish: Bright zinc plating with post-plate bake mitigates hydrogen embrittlement—fully RoHS compliant.
- Monster Quality: Tight tolerances, batch inspection, and fast U.S. shipping.
