OTC Tools 1912 3-7/8" 3/4" Drive 6-Point Wheel Bearing Locknut Socket

The OTC Tools 1912 is a heavy-duty wheel bearing locknut socket designed for professional technicians working on trucks, trailers, and heavy equipment. This 3-7/8" (flat-to-flat) 6-point socket features a 3/4" square drive and provides the specialized design needed to safely remove and install wheel bearing locknuts without damage.

Key Features:

• 3-7/8" 6-point opening size for precise flat-to-flat locknut engagement
• 5 inches deep to ensure proper spindle clearance during service
• Constructed from high-strength steel that resists rounding out under high torque loads
• 3/4" square drive compatible with torque wrenches for proper locknut torque specifications
• Can be used with extensions to provide necessary clearance in tight wheel assemblies
• Designed for manual tool use only - not intended for impact tools

This socket is part of the OTC 9850 6-Point Wheel Bearing Locknut Socket Set with Tool Board, but is also available individually for replacing lost or damaged sockets. The 6-point design distributes torque evenly across the locknut flats, reducing the risk of fastener damage. Always measure your locknut from flat to flat before selecting socket size to ensure proper fit.

Note: Use with impact tools will void the warranty. Designed for use with 3/4" square-drive manual tools only.
