Never Let a Rounded Bolt Stop You Again

Meet the GEARWRENCH 5 Piece Bolt Biter Metric Wrench Insert Set – the ultimate solution for one of the most frustrating jobs in the shop: rounded, frozen, or damaged fasteners. We've all been there: a bolt head is stripped, and a regular wrench or socket just slips, making the problem worse. Traditional extractors are often bulky and only work in one direction. The Bolt Biter system changes the game.

These inserts are an incredible 70% thinner than standard extraction tools, allowing you to slide them into tight spaces where no socket could ever fit. Use them with any 6-point, 12-point, or even ratcheting wrench in your toolbox. The revolutionary bi-directional design not only grips to remove the toughest stuck bolts but also allows you to tighten damaged fasteners, making it perfect for emergency repairs. This set isn't just a tool; it's a timesaver.

Key Features

  • Bi-Directional Design: Safely grips to remove or tighten damaged and rounded-out fasteners.
  • Tapered Entry: Allows the insert to easily and quickly seat on a damaged fastener head.
  • Ultimate Versatility: Designed to work perfectly with static, ratcheting, or open-end wrenches.
  • Ultra-Thin Profile: At 70% thinner than traditional extractors, it provides access to the most confined spaces.
  • Magnetic Retention: Securely holds the insert inside the wrench for easy one-handed use.
  • High-Visibility Markings: Laser-etched sizes are easy to read, helping you grab the right tool quickly.
  • Durable Construction: Made from tough Chrome-Molybdenum (Cr-Mo) with a Manganese Phosphate finish for corrosion resistance.
