Description
Monster Overview:
Achieve flush, high-strength joints in structural sheet and channel with 3/8-16 × 1″ Phillips Flat Head Thread-Cutting Screws, Type 23, Zinc-Bake from Monster Bolts. The 82 ° countersunk head seats cleanly with no protrusion, while the Type 23 triangular chip-relief pocket clears 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 supplies reliable corrosion protection and full RoHS compliance. These screws are fully threaded for maximum grip along the entire 1″ shank.
Monster Features:
- Flush-Fit Flat Head: 82 ° countersink sits level with the surface for snag-free finishes.
- Type 23 Cutting Point: Large triangular chip pocket ejects shavings for smoother cutting and reduced drive torque.
- Phillips Drive: #4 Phillips recess (for 3/8″ screws) 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.
