Description
Monster Overview
Clamp like a bolt—no backing nut required. #10-24 Slotted Hex-Washer Thread-Cutting Screws are forged from 410 martensitic stainless steel and heat-treated to Rockwell C38-45, marrying stainless corrosion resistance with carbon-steel strength. The indented hex head + integral washer spreads load and covers oversize holes, while a wide flat-blade slot provides a backup drive in tight quarters. A Type F fluted point taps clean internal threads in a pre-drilled or punched hole; chips exit through the flute—no chip cleanup, welds or nuts. Each screw is passivated and finished with a factory dry-wax film for predictably low seating torque.
Monster Features
- Dual-Drive Head: Indented #10 hex (¼″ wrench) plus broad slot—socket, nut-runner or flat driver.
- Washer Head Advantage: Enlarged bearing surface resists pull-through and helps seal joints in thin sheet.
- Type F Cutting Point: UN C machine thread with fluted slot—forms threads in 0.060–0.180″ steel plate or dense hardwood; chips exit cleanly.
- Material Edge: 410 stainless is magnetic, heat-hardened and tougher than 18-8 yet still stainless-corrosion-resistant.
- Finish & Lube: Passivated surface + factory dry-wax (silicone-free) for consistent clamp load.
- Bulk Packaging: Factory-sealed master cartons—ideal for trailer fabrication, marine fixtures, food-equipment frames & stainless construction projects.
