Monster Overview:
These 5/16″-18 6-Lobe (Torx) Flat-Countersunk Thread-Cutting Screws seat flush while tapping mating threads in pre-drilled or punched holes—perfect for steel deck plates, trailer floors, dock boards and hardwood facings. Heat-treated carbon-steel blanks receive a bright zinc electro-plate, are hydrogen-relief baked, then factory dry-waxed for ultra-low, repeatable drive torque.
