Stop Cursing at Rounded Bolts: Grip and Rip Them Out.

There's nothing more frustrating than a 12mm bolt head that's rounded off or frozen. The job stops, and the knuckles get busted. Enter the GEARWRENCH 86184 Bolt Biter. This isn't just another extractor; it's a revolutionary nut driver. Its patented technology grips onto damaged, frozen, or rounded fasteners instead of cutting into them. This means it not only gets them out but can even be used to tighten them. Built from tough, impact-ready Chrome Molybdenum steel, this single 12mm driver is the specialist you need in your toolbox for the bolts everyone else gave up on.

Key Features

  • Bi-Directional Design: Grips to both remove or tighten damaged, rounded, and frozen fasteners.
  • 50X Longer Life: Revolutionary design grips instead of cuts, avoiding wear and delivering a 50x longer life than competitors.
  • Impact-Ready: Torsion zone and Chrome Molybdenum (Cr-Mo) alloy steel construction provide exceptional strength for high-torque impact applications.
  • Tapered Entry: Easily seats on damaged fasteners for a secure, non-slip grip.
  • High-Visibility Markings: Laser-etched size (12- mm) is easy to read and won't wear off.
