Durable Bulk 1/4″-20 Phillips Flat-head Thread-cutting Screws — Type F, Bright-zinc Steel Limited Time 50% Off [DF1dju78]

Monster Overview:

These 1/4″-20 Phillips Flat-Head Thread-Cutting Screws combine bolt-like strength with a flush, snag-free profile—perfect for trailer decks, dock boards, steel flooring and hardwood-to-steel assemblies. Heat-treated carbon steel receives a brilliant bright-zinc electro-plate, is hydrogen-relief baked to eliminate embrittlement, and finished with a factory dry-wax film for reliably low drive torque. The Type F fluted point taps clean internal 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 #3 recess—high torque with minimal cam-out.
• Type F Cutting Point: UNC machine thread with fluted slot—forms threads in 0.050–0.200″ steel plate or dense hardwood; chips exit cleanly.
• Bright-Zinc Finish: RoHS-compliant plating, hydrogen-relief baked, topped with factory dry-wax for consistent clamp load.
• Material: Heat-treated carbon steel delivers exceptional tensile and shear strength.
• Bulk Packaging: Sealed master cartons—ideal for OEM fabrication, dock builders & trailer shops.
