Description
Monster Overview:
Bulk #8-32 Slotted Indented Hex-Washer Head Taptite Alternative Thread-Rolling Screws from Monster Bolts give you the flexibility of a dual-drive design—turn them with a 1/4″ hex driver or a flat-blade screwdriver. Their trilobular bodies roll-form tough, reusable threads in untapped holes, slashing assembly time while resisting vibration in aluminum, mild steel, brass, and plastics.
A bright zinc bake & wax finish adds lubricity for lower drive torque plus RoHS-compliant corrosion protection. Perfect for HVAC and sheet-metal work, appliance frames, and general-manufacturing builds that need a flange-style head with the backup of a slot.
Monster Features:
- Combo Slot + Hex Drive: Use whichever tool is handy—great for tight spots or field repairs.
- Built-In Washer: Indented hex-washer (flange) head spreads load and protects finishes.
- Thread-Rolling Efficiency: Forms internal threads—no taps, chips, or secondary ops.
- Vibration Resistance: Interference fit & work-hardened threads stay tight under dynamic loads.
- Smoother Installs: Trilobular profile and wax top-coat cut friction for faster assembly.
