Description
Monster Overview:
Miniature strength for electronics chassis, light-gauge steel housings and dense hardwood trim — these #4-40 × ¼″ Unslotted Indent Hex-Washer Head Thread-Cutting Screws install fast with a 5⁄32″ nut-setter. Heat-treated carbon steel carries a bright zinc electro-plate, is hydrogen-relief baked to prevent embrittlement, and finished with a factory dry-wax film for ultra-low seating torque. The captive washer spreads load, while 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:
- Head / Drive: One-piece unslotted indent hex-washer (5⁄32″ AF) — smooth forge won’t trap swarf; captive washer grips thin steel or wood.
- Type F Cutting Point: UNF machine thread with fluted slot — forms threads in 0.020–0.050″ steel sheet or dense hardwood.
- Finish: Bright-zinc (RoHS) + light oil, baked for hydrogen relief, topped with factory dry-wax for repeatable clamp load.
- Material: Heat-treated carbon steel for high tensile and shear strength.
- Bulk Packaging: Sealed master cartons — ideal for appliance assembly, electronics fabrication & HVAC shops.
