MM Stud runner sockets

MM stud runner sockets (also called stud installer sockets) are specialty sockets used to install or remove threaded studs more efficiently while helping reduce damage to the stud threads (application dependent; verify per listing). They’re commonly used in automotive repair, industrial maintenance, and equipment service when you need to run studs in or out during assembly, teardown, or replacement work (application dependent). Depending on the design, stud runner sockets may grip the stud internally (rather than on an external hex) to help provide consistent engagement across a range of stud lengths (per listing).
