Description
Monster Overview:
Achieve clean, low-profile assemblies with #4-40 Phillips Flat Head Thread-Cutting Screws, Type 23, Zinc-Bake from Monster Bolts. The 82 ° countersunk head sits flush with the surface, while a Type 23 triangular chip-relief pocket ejects swarf as it cuts—reducing drive torque and leaving crisp internal threads in steel, aluminum, and plastics.
Bright zinc plating followed by a hydrogen-relief bake delivers dependable corrosion protection and full RoHS compliance. Choose fully-threaded screws in handy 5⁄16″ or 3⁄8″ lengths—perfect for electronics housings, hobby builds, and small appliance repair.
Monster Features:
- Flush-Fit Flat Head (82°): Sits level for snag-free, professional finishes.
- Type 23 Cutting Point: Large triangular chip pocket clears shavings for smoother cutting and lower drive torque.
- Phillips Drive: #1 Phillips recess offers precise, cam-out-resistant engagement.
- 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.
