GearWrench 84786 Bolt Biter™ 10-Piece Damaged Fastener & Screw Extractor Set

The GearWrench 84786 Bolt Biter™ 10-piece screw extractor set removes, loosens, and tightens stubborn, rusted, rounded, or snapped fasteners ranging from 1/4-inch to 3/4-inch (M5 to M16). Forged from high-strength alloy steel with a corrosion-resistant black oxide coating, this professional extraction kit delivers up to 50 times longer service life than standard extractors by utilizing tapered side and tip cutting edges that bite securely into damaged bolt heads. Outfitted with a bi-directional design for walking frozen bolts out of housings, a hex base compatible with hand ratchets and power impact tools, matching extraction drill bits, and a rugged GEARCASE™ storage organizer, it equips automotive mechanics, industrial technicians, and maintenance professionals with reliable extraction torque.

Best Used For:

  • Automotive Engine Block and Exhaust Manifold Repair: Extracting snapped, rusted, or sheared manifold studs and engine block bolts without damaging surrounding threads.
  • Industrial Machinery MRO Restoration: Removing stripped hex-head bolts and rounded fasteners on heavy plant machinery and mechanical housings.
  • Commercial Construction and Equipment Servicing: Extracting damaged structural fasteners, frozen carriage bolts, and stripped screws on jobsite equipment.

Key Performance & Safety Features

  • Dual Tapered Cutting Geometry: Advanced side and tip cutting edges grip damaged fastener heads securely to prevent slipping under extreme extraction torque.
  • Bi-Directional Fastener Control: Innovative design enables both loosening and tightening actions, allowing technicians to rock frozen bolts back and forth.
  • Power Tool Hex Base Compatibility: Standard hex base design allows seamless connection with hand tools, impact drivers, and power socket wrenches.
  • Industrial Black Oxide Finish: Chemical surface coating repels moisture, oil residue, and shop corrosion for extended tool lifespan.
  • High-Visibility Laser Markings: Laser-etched size dimensions ensure rapid tool identification and selection in dimly lit service bays.
  • Included Extraction Drill Bits: Comes complete with 5 matching drill bits for pre-drilling snapped bolts prior to extractor insertion.
