Description
Monster Overview:
Achieve a flush, snag-free finish with bulk #4-20 Phillips Flat Head PT 48-2 Thread-Forming Screws from Monster Bolts. The 82 ° countersunk head seats smoothly in plastic panels, while the tri-lobular Plastite® profile cold-flows thermoplastic to create high-holding, chip-free internal threads—no tapping, no debris. Each screw is heat-treated carbon steel, bright-zinc electro-plated and baked to relieve hydrogen embrittlement, then factory wax-coated for consistently low drive torque. Master cartons keep per-unit cost minimal for high-volume builds.
