Crescent Impact Nut Driver Extractor CAVXM1D24 3/8 Inch Bolt Biter Tool (1-7/8 Length Bi-Directional Tapered Cr-Mo Magnetic Fastener Extraction)

Crescent CAVXM1D24 3/8" x 1-7/8" Bolt Biter™ Magnetic Impact Nut Driver & Extractor

The Crescent CAVXM1D24 3/8-inch x 1-7/8-inch Bolt Biter™ impact nut driver and extractor drives new fasteners and removes severely rounded, corroded, painted, or stripped 3/8-inch hex-head screws across automotive assemblies, mechanical equipment, and industrial machinery housings. Engineered with an innovative bi-directional tapered socket geometry, this dual-function impact accessory re-engages compromised fastener flanks without slippage while maintaining full forward driving capabilities. Outfitted with impact-grade alloy steel construction engineered to yield up to 50x longer operational life in high-torque impact guns, an integrated industrial rare-earth holding magnet that secures hardware in blind overhead runs, and a corrosion-resistant black oxide finish, it equips automotive mechanics, industrial technicians, and MRO service specialists with instant fastener extraction without damaging surrounding assemblies.

Best Used For:

• Automotive Chassis and Suspension Maintenance: Backing out stripped, rusted, or weathered 3/8-inch hex frame bolts, splash shield screws, and bracket fasteners in tight engine bays.
• Industrial Machinery and Equipment Service: Driving and removing corroded 3/8-inch hex fasteners on heavy production equipment, pumps, and structural housing guards.
• High-Torque Production Driving and Assembly: Installing new 3/8-inch hex fasteners rapidly using impact drivers without rounding fastener heads or dropping nuts during overhead work.

Key Performance & Safety Features

• Bi-Directional Extraction & Driving: Patented socket geometry grips damaged fasteners in both tightening and loosening directions, enabling both screw installation and extraction with one tool.
• Tapered Entry Flutes: Specialized internal entry profile seats effortlessly onto rounded 3/8-inch hex heads on the first try, eliminating manual file prep or hammer-on extractor steps.
• 50X Impact-Rated Durability: Heat-treated alloy steel core withstands peak torque spikes, delivering up to 50x longer working life than standard nut drivers.
• Industrial Magnetic Retention: High-strength integrated magnet holds screws and nuts firmly seated inside the socket during awkward horizontal and overhead reaches.
• Universal 1/4" Quick-Connect Hex Shank: Power groove shank fits standard 1/4-inch impact driver quick-release chucks and conventional drill chucks without spinning out.
• High-Visibility Laser Etching: Permanent size and model markings allow rapid identification inside crowded bit cases and tool pouches.
• Corrosion-Resistant Black Oxide Coating: Protective chemical conversion finish guards against moisture, rust, motor oil, and jobsite chemical exposure.

Technical Specifications

Pro-Tip: When breaking loose a seized or rusted 3/8-inch hex bolt in tight automotive spaces, maintain steady forward pressure on your impact gun before pulling the trigger; allowing the tapered internal flutes to seat firmly over the degraded corners ensures immediate biting action without slipping or rounding the bolt further.
