OTC Tools Pinion Locknut Socket Drive

The OTC Tools Pinion Locknut Socket line is made for installing and removing the yoke locknuts on truck transmissions and differentials. These heavy-duty pinion nut sockets are built with the clearance a yoke and locknut assembly needs. You don't have to modify a standard socket or work around poor access.

Key Features:

• Purpose-built clearance: The design fits around the yoke and locknut assembly on a wide range of truck applications.
• No socket modification: You don't need to grind or alter a standard socket to reach the locknut.
• Deep, extended-reach design: Extra usable depth lets the socket seat fully on recessed pinion locknuts.
• 6-point engagement: The socket grips the locknut flats securely and resists rounding.
• Durable steel construction: OTC builds the sockets for the torque of heavy-duty drivetrain service.
• Square drive design: The socket works with compatible drive tools for loosening and torquing the locknut.

OTC (Owatonna Tool Company) is a long-standing name in professional automotive and heavy-duty specialty tools. These pinion locknut sockets are offered in a range of sizes to suit different truck pinion nut applications. They suit professional technicians and shops that do differential and driveline work, and they help save time on ring and pinion service.
