# Proto J5212SPL 5212SPL 3/8 DR SPLINE SCKT 3/8" #12 PROTO | JensenTools

**Manufacturer:** Proto  
**MPN:** `J5212SPL`

The Proto J5212SPL 3/8-Inch Drive Spline Socket, Number-12, 3/8-Inch is designed for high-performance torque applications. It is intended for use in areas requiring high tensile strength fasteners, such as military and commercial aircraft. The socket helps tighten high-strength bolts to high torque, reducing the force required to turn standard fasteners by allowing the torque load to be moved away from the corners. It delivers twice the torque of 12-point wrenches on spline fasteners.
