Description

Conquer Frozen and Stripped Fasteners with the GearWrench Bolt Biter™ Impact Extraction Screwdriver

The GearWrench 86092 Bolt Biter™ 1/4" x 4" Slotted Extraction Screwdriver combines the everyday convenience of a standard screwdriver with the heavy-duty power of a dedicated impact driver. Specifically engineered to loosen rusted, stripped, or stubborn screws, this tool features a high-performance steel handle end cap designed for repetitive striking. When the end cap is struck, an internal mechanism transfers the shock to rotate the heat-treated alloy steel shaft 12 degrees, providing the torque necessary to break free even the most difficult fasteners without damaging the surrounding material.

Beyond its extraction power, the Bolt Biter™ is built for comfort and long-term durability on the jobsite. The ergonomic tri-lobe dual material handle offers a perfect balance of strength and grip efficiency, while the specialized "Speed Zone" design allows for rapid rotation in low-torque applications. The blade is finished in rust-resistant nickel chrome with a non-slip black oxide tip for a secure fit in every fastener. Whether you are working in automotive, industrial, or home repair environments, this solvent-resistant tool is designed to exceed ASME standards and provide professional results in the toughest conditions.

Key Features

  • 12-Degree Impact Rotation: Internal spring-loaded mechanism converts strikes into rotation to remove frozen or rounded screws.
  • Striking End Cap: High-performance steel end cap is built to withstand repetitive impacts from a hammer.
  • Tri-Lobe Ergonomic Handle: Dual material handle provides optimal grip and comfort for high-torque manual turning.
  • Non-Slip Black Oxide Tip: Precision-machined tip ensures a secure fit in the fastener to prevent further stripping.
  • Speed Zone Design: Optimized handle shape allows for faster rotation during the threading and unthreading process.
  • Chemical Resistant: Oil and solvent-resistant handle ensures a longer tool life in harsh garage or shop environments.

Pro-Tip: When dealing with a severely rusted screw, apply a drop of penetrating oil and let it sit for a few minutes before using the Bolt Biter. Ensure the tip is fully seated and keep firm downward pressure while striking the end cap; this maximizes the 12-degree rotation and prevents the bit from jumping out of the slot.
