MonsterBolts 1/2-13 slotted indented hex-washer head Taptite thread-rolling screws bulk

Monster Overview:

Bulk 1/2-13 Slotted Indented Hex-Washer Head Taptite Alternative Thread-Rolling Screws from Monster Bolts give you true field flexibility—drive them with a 5/16″ flat-blade screwdriver in a pinch or power them home with a 3/4″ nut-driver for maximum torque. The beefy trilobular body roll-forms reusable threads in untapped steel and aluminum, shaving production time while locking up tight against vibration.

A bright zinc bake & wax finish supplies lubricity for lower drive torque plus RoHS-compliant corrosion protection. Perfect for truck bodies, heavy equipment panels, structural sheet-metal, and other fabrications that need a rugged flange-style head with a backup slot.

Monster Features:

  • Combo Slot + Hex Drive: Two tool options (slot or hex) for job-site versatility and easy service.
  • Integrated Washer Flange: Indented hex-washer head spreads load—no separate washer needed.
  • Thread-Rolling Efficiency: Forms internal threads in one pass—no taps, chips, or secondary ops.
  • Vibration Resistance: Interference fit + work-hardened threads keep joints tight on the road or in the plant.
  • Smoother Installs: Trilobular profile and wax top-coat cut friction for faster, lower-torque runs.
