OTC Tools 1976 Pinion Locknut Socket Drive - 2-1/8 6-Point 3/4

The OTC Tools 1976 is a heavy-duty pinion locknut socket designed specifically for servicing truck transmissions and differentials. This 2-1/8" 6-point socket is engineered with the correct clearance to access yoke and locknut assemblies without modification, saving time and preventing damage to standard sockets.

Key Features:

• 2-1/8" opening size with 6-point design for superior grip and reduced fastener rounding
• 3" usable depth with 4" overall length provides extended reach for recessed locknuts
• 3/4" square drive for use with manual impact wrenches and breaker bars
• Purpose-built clearance eliminates the need to grind or modify standard sockets
• Compatible with a variety of truck transmission and differential assemblies

This socket is designed exclusively for use with 3/4" square drive manual tools and should not be used with power impact tools. The 6-point design resists rounding and provides maximum contact with locknut flats, making it ideal for high-torque applications on heavy-duty vehicles.
