Description
Monster Overview:
Bulk #10-24 Slotted Hex-Washer Taptite Alternative Thread-Rolling Screws blend dual-drive convenience with the strength of martensitic 410 stainless steel. Spin them in quickly with a 5/16″ nut-driver or service them later with a flat-blade screwdriver. Their trilobular shank roll-forms durable, reusable threads in untapped holes—cutting assembly time while resisting vibration in aluminum, mild steel, brass, and plastics.
The alloy is passivated & wax-coated for a pristine surface, added lubricity, and RoHS-compliant corrosion protection. Perfect for appliance frames, HVAC sheet-metal, marine panels, and any build that needs a stainless flange head with a backup slot.
Monster Features:
- High-Strength 410 SS: Heat-treated martensitic stainless out-hardens 18-8.
- Combo Slot + Hex Drive: Two tool options (slot or hex) for field versatility.
- Integrated Washer Flange: Indented hex-washer head spreads load—no loose washer.
- Thread-Rolling Efficiency: Forms internal threads in one pass—no taps or chips.
- Vibration Resistance: Interference fit & work-hardened threads keep joints tight.
