Description
Monster Overview:
Create flush, snag-free fastenings in thin plastic with bulk #2-28 × 3⁄16″ Phillips Flat-Undercut Head PT 48-2 Thread-Forming Screws from Monster Bolts. The shortened undercut 82° head lets a full-size #2 head seat flush in very thin bosses or sheet-plastic lids, while the tri-lobular Plastite® flank cold-flows thermoplastic to form high-holding, chip-free threads—no taps, no cleanup. Each screw is heat-treated carbon steel, bright-zinc electro-plated and baked to drive out hydrogen embrittlement, then factory wax-coated for ultra-low seating torque. Master cartons keep your per-unit cost razor-low for volume production.
