Description
Monster Overview
When you need washer-level bearing area in a micro fastener, choose our #4-40 × ¼″ Phillips Truss Thread-Cutting Screws. The wide truss head spreads load to protect thin sheet or PCB laminates, while the cross-recess Phillips drive speeds assembly. Each screw is forged from heat-treated carbon steel, coated in bright-zinc plating, hydrogen-relief baked for safety, then factory dry-waxed for ultra-low, repeatable seating torque.
Monster Features
- Wide Truss Head — built-in washer prevents pull-through on thin plate and FR-4 panels.
- Phillips Drive — #1 cross recess installs quickly with common miniature drivers.
- Type F Cutting Point — #4-40 UNF thread with fluted slot taps clean threads in 0.015–0.035″ steel sheet or dense hardwood; chips exit cleanly.
- Bright-Zinc Finish — RoHS-compliant plating, hydrogen-relief baked, factory dry-waxed for consistent clamp load and anti-seize protection.
- Material — heat-treated carbon steel delivers high tensile & shear strength at miniature scale.
- Bulk Packaging — sealed master cartons—ideal for OEM electronics, precision fabrication & service kits.
