Description
Monster Overview:
Optimize countersunk assemblies with #12-24 Phillips Flat Undercut Head Thread-Cutting Screws, Type 23, Zinc-Bake from Monster Bolts. The undercut flat head provides full bearing in thin sheet while leaving extra thread engagement. A Type 23 triangular chip-relief pocket at the tip clears swarf as it cuts—reducing drive torque and delivering smoother internal threads in steel, aluminum, and other ductile materials.
Bright zinc plating followed by hydrogen-relief bake offers classic corrosion protection with RoHS compliance. Fully-threaded screws ship fast from the USA and are backed by Monster Bolts’ industry-leading support.
Monster Features:
- Undercut Flat Head: Shallow 82 ° profile maximizes thread engagement in thin sheet or brittle plastics.
- Type 23 Cutting Point: Triangular chip-relief slot for smooth cutting and lower drive torque.
- Phillips Drive: #2 Phillips recess ensures reliable, cam-out-resistant installation.
- Zinc-Bake Finish: Bright zinc plating with post-plate bake mitigates hydrogen embrittlement.
- Monster Quality: Tight tolerances and batch inspection meet our exacting standards.
