Overview
A spring plunger uses a spring-loaded pin in a threaded body. The body screws into a fixture with a hex socket drive, and the pin presses into a mating hole or groove to position, index, or hold a part. The TS series is stainless steel throughout; the TSTG series uses a carbon steel body. Sizes cover M3 to M12.
