Description

Monster Overview:
Need flush-seating, vibration-proof fasteners for dock framing, trailer decks, steel flooring or hardwood-to-steel joints? These 3/8″-16 × 1 ½″ Phillips Flat-Head Thread-Cutting Screws are forged from heat-treated carbon steel, then finished with a brilliant bright-zinc electro-plate, hydrogen-relief baked, and factory dry-waxed to keep drive torque low and predictable. The Type F fluted point taps clean female threads in a pre-drilled or punched hole; chips clear through the flute—no nut required.
Monster Features:
- Flush Seating & Drive: 82° flat countersunk head with Phillips #4 recess — large-diameter driver for high torque without cam-out.
- Type F Cutting Point: UNC thread with fluted slot — forms internal threads in 0.090–0.250″ steel plate or dense hardwood; chips exit cleanly.
- Bright-Zinc Finish: RoHS-compliant plating, hydrogen-relief baked, topped with factory dry-wax film for consistent clamp load.
- Material: Heat-treated carbon steel delivers exceptional tensile and shear strength.
- Bulk Packaging: Sealed master cartons — perfect for OEM steel fabrication, dock builders & trailer shops.
