Description

Monster Overview:
Upgrade your builds with 1/4-20 Phillips Pan Head Thread-Cutting Screws, Type 23, Black Oxide from Monster Bolts. Type 23 screws feature a triangular clearance slot at the tip, removing more material than line-slotted Type 1 or Type F styles. The result: lower driving torque, cleaner internal threads, and reduced chip clogging in thicker sheet metal, aluminum, or mild steel.
An oil-treated black-oxide finish delivers a low-glare appearance and mild corrosion protection while remaining fully RoHS compliant. Choose from ½″ or ¾″ fully-threaded lengths—all backed by fast US shipping and Monster Bolts’ renowned customer support.
Monster Features:
- Type 23 Cutting Point: Large triangular chip-relief pocket for smooth cutting and easier drive-in.
- Phillips Drive: #3 Phillips recess offers positive engagement with common drivers.
- Pan Head Profile: Wide bearing surface ideal for sheet-metal assemblies and electrical enclosures.
- Black Oxide Finish: Low-gloss look with a light oil seal—mild rust resistance, no plating buildup.
- Quality You Trust: Manufactured to tight tolerances and batch-inspected to Monster Bolts standards.
