Revolutionize Damage Recovery: GearWrench Bolt Biter Wrench Inserts for Frozen and Rounded Fasteners

The GearWrench 86193 30-Piece Bolt Biter SAE/Metric Wrench Insert Set is the ultimate professional solution for extracting the most stubborn, frozen, and rounded fasteners. These innovative inserts feature a revolutionary bi-directional gripping design that allows for both removing and tightening damaged bolts with equal efficiency. Unlike traditional extraction sockets that are often too bulky for modern engine bays, the Bolt Biter inserts are 70% thinner than standard extraction tools. This ultra-slim profile enables them to fit inside your existing ratcheting or open-end wrenches, providing a high-torque extraction solution in tight, confined spaces where other tools simply cannot reach.

Engineered for industrial-grade durability, each insert is manufactured from high-strength Chrome-Molybdenum (Cr-Mo) steel and finished with a Manganese Phosphate coating for superior corrosion resistance. The set utilizes a sophisticated magnetic retention system that ensures a secure, "locked-in" fit inside your wrench, while the tapered entry allows each insert to seat quickly and safely on damaged fastener heads. With a comprehensive range of dual-sized and "minus-size" inserts, this 30-piece kit covers a vast array of SAE and Metric fasteners, even those heavily reduced by rust or wear. Housed in a durable injection-molded case with high-visibility laser-etched markings, the GearWrench Bolt Biter set ensures you stay organized and productive on even the most frustrating repair jobs.

Key Features

• Minus-Size Increments: Specialized minus-sizes fit fasteners that have been reduced in size due to heavy rust or severe rounding.
• Chrome-Molybdenum Construction: Forged from Cr-Mo steel for maximum strength and finished with Manganese Phosphate for durability.

What's Included

• (30) Bolt Biter SAE and Metric Wrench Inserts (Range: 1/4" to 3/4" / 7mm to 19mm)
• (1) Heavy-Duty Injection Molded Carrying Case

Specifications

Pro-Tip: For the most effective extraction, start with the standard size insert that matches the fastener. If the standard size slips due to extreme rounding, switch to the corresponding "minus-size" insert. Because these inserts are bi-directional, you can use them with a ratcheting wrench to rock a frozen fastener back and forth to break the surface tension and rust bond more efficiently.
