New Buffalo 84777 Bolt Biter Drive Impact Extraction Socket - 3/8 19mm 3/4

The New Buffalo 84777 Bolt Biter™ Impact Extraction Socket is a professional-grade 3/8" drive socket engineered to remove or tighten damaged, rounded, and corroded fasteners. Sized at 19mm / 3/4", this dual-sized socket bridges SAE and metric applications in one tool, making it an essential addition to any mechanic's impact socket set.

Built from chrome molybdenum alloy steel (Cr-Mo), the 84777 delivers exceptional strength and long-lasting durability under high-torque impact conditions. New Buffalo's proprietary Bolt Biter™ geometry is engineered to deliver up to 5x greater torque output and up to 10x longer impact life compared to other extraction sockets on the market.

Key Features:

• Bi-directional design — removes or tightens damaged fasteners with equal effectiveness
• Tapered entry — allows the socket to seat quickly and securely on damaged or deformed fastener heads
• Minus-size geometry — fits a wider range of damaged fasteners by biting into the fastener's surface
• Dual SAE/Metric sizing — designed to work with both 19mm and 3/4" fasteners
• Square drive with hex base — compatible with impact guns, ratchets, wrenches, and pliers
• Chrome molybdenum alloy steel (Cr-Mo) — provides superior strength and durability for demanding impact applications
• Black oxide finish — resists corrosion for extended tool life
• High-visibility laser-etched markings — allow quick size identification even in low-light conditions
• Up to 10x longer impact life vs. other impact extraction sockets
• Up to 5x greater torque output vs. other impact extraction sockets

The New Buffalo Bolt Biter™ extraction socket is the right tool for tackling seized bolts and stripped fasteners encountered in automotive repair, heavy equipment maintenance, and professional shop use. The 3/8" drive format ensures broad compatibility with standard impact drivers and ratchets.
