GEARWRENCH - ACH 86190 5 Piece SAE Bolt Biter Insert Set

The GEARWRENCH - ACH 86190 5 Piece SAE Bolt Biter Insert Set provides a precision solution for stubborn fasteners in automotive and industrial service. Designed as SAE bolt biter inserts, each piece is engineered to grip rounded, damaged, or corroded bolt heads for removal using compatible impact tools. The set covers common SAE sizes so technicians can address a variety of repair tasks without improvising with ill-fitting sockets.

Automotive Impact Wrench Compatibility

These Bolt Biter inserts are optimized for use with impact-ready drives and adapters, delivering secure engagement when paired with an automotive impact wrench. Hardened contact points and a serrated internal profile help the insert bite into damaged fasteners, reducing slippage and minimizing tool wear. The SAE sizing aligns with standard vehicle fasteners, making the set appropriate for brake, suspension, and drivetrain work.

Compact Impact Wrench Applications

The compact design of the inserts supports tight-space service where a compact impact wrench is preferred. Low-profile geometry allows better access around brake calipers, engine components, and other confined areas. Technicians benefit from the combination of bite performance and space-conscious design when tackling delicate or hard-to-reach repairs.

Professional And Heavy Duty Impact Wrench Durability

Built for professional impact tool environments, the inserts resist deformation during high-torque applications commonly encountered with heavy duty impact wrenches. Quality heat treatment enhances toughness and extends service life under repeated impacts. The set is suitable for shop use as well as mobile service vans where durable, reliable accessories are essential for productivity.

Each insert is labeled for quick size identification and stored in a compact organizer for convenient transport and on-the-bench access. The GEARWRENCH - ACH 86190 set is a targeted accessory for technicians who need bolt extraction capability without oversizing their toolkit. Fast shipping.
