Monster Overview:
Crank assembly throughput with 1/4″-10 Serrated Hex-Washer Head PT 48-2 Thread-Forming Screws from Monster Bolts.
• Head: External unslotted indent hex-washer for socket or nut-runner drive.
• Serrations: Under-head teeth bite the mating surface to lock against vibration—no washers needed.
• Thread: Plastite-alternative tri-lobular flank cold-flows thermoplastic, forming chip-free internal threads—no taps, no debris.
Each heat-treated carbon-steel screw is bright-zinc plated, hydrogen-relief baked, then factory wax-lubed for ultra-low drive torque. Bulk master cartons keep your per-unit cost rock-bottom.
