Description
Monster Overview:
Sized for electronics chassis, miniature sheet-metal housings and dense hardwood trim, these #4-40 × ⅜″ Phillips Flat-Head Thread-Cutting Screws seat flush while tapping clean threads in a pre-drilled or punched hole. Heat-treated carbon-steel blanks wear a tough black-oxide conversion coat, then a factory dry-wax film for ultra-low, repeatable drive torque.
Monster Features:
- Flush Seating: 82° flat countersunk head leaves surfaces smooth and snag-free.
- Classic Drive: Phillips #0 recess—ideal for precision assembly tools.
- Type F Cutting Point: UNF thread with fluted slot—forms internal threads in 0.020–0.050″ steel sheet or dense hardwood; chips exit cleanly.
- Finish: Black-oxide (oil-sealed) plus factory dry-wax for smooth installation and indoor corrosion protection.
- Material: Heat-treated carbon steel provides high tensile and shear strength.
- Bulk Packaging: Sealed master cartons—ideal for electronics OEMs, appliance lines & HVAC shops.
