Description

Extract and Drive Damaged Fasteners with Revolutionary Bi-Directional Grip Technology

The Crescent Apex Bolt Biter 5/16-inch impact nut extractor and driver is the ultimate solution for professionals dealing with stubborn, rusted, or rounded-off fasteners. Unlike traditional extraction tools that only work in one direction, this innovative tool features a bi-directional design that allows you to both remove and tighten damaged nuts and bolts with ease. Whether you are performing automotive repairs, industrial maintenance, or home renovations, the Bolt Biter eliminates the frustration of stripped hex heads by gripping no matter how damaged the fastener has become.

Built for the most demanding environments, this extractor is manufactured from premium Chrome Molybdenum (Cr-Mo) alloy steel and finished with a corrosion-resistant black oxide coating. It is fully impact-rated to withstand the high torque of modern drivers and is engineered to provide up to 50x longer life than standard competitors. The tapered entry design ensures the tool grabs onto hardware quickly, while the 1/4-inch hex shank provides universal compatibility with your existing impact drivers and drills. High-visibility laser-etched markings ensure you can identify the correct 5/16-inch size instantly in a crowded tool bag.

Key Features

  • Bi-Directional Gripping: Revolutionary design allows for both the removal and tightening of ruined fasteners.
  • Extreme Durability: Engineered for high-torque applications with up to 50x longer life in impact use.

Pro-Tip: When dealing with a severely rusted 5/16" bolt, apply a small amount of penetrating oil and let it sit for a few minutes before use. Use your impact driver on a medium setting to allow the Bolt Biter's tapered flutes to "bite" into the metal, then increase torque to break the fastener free without snapping the head.
