OTC 1918 Wheel Bearing Locknut Socket 6-Point 4-7/8 Inch

The OTC 1918 is a professional-grade wheel bearing locknut socket engineered for safe and efficient removal and installation of truck wheel bearing locknuts. This specialized socket features a 6-point design with a 4-7/8 inch flat-to-flat opening size, specifically designed to grip locknuts securely without rounding under high torque loads.

Key Features:

• Constructed from high-strength steel for exceptional durability and resistance to rounding
• 6-point configuration provides maximum contact surface for secure grip
• 4-7/8 inch opening size (flat-to-flat measurement)
• 5 inches deep to ensure proper spindle clearance during operation
• 3/4 inch square-drive design compatible with extensions and torque wrenches
• Designed for use with manual drive tools only

Important Usage Notes: This socket is engineered exclusively for use with 3/4 inch square-drive manual tools. It is NOT intended for use with impact tools, as impact tool use will void the socket's warranty. To determine the correct socket size for your application, measure your locknut from flat to flat. The precision-engineered design allows for easy locknut removal and installation, even with wide-rim wheels, by using a long extension to provide necessary clearance.

Part of the trusted OTC Tools product line, this wheel bearing locknut socket delivers the professional-grade performance and reliability that technicians have depended on since 1925. Ideal for heavy-duty truck maintenance and repair applications.
