Indexing plungers, also known as locking plungers, are primarily used to secure or release plug connections on machines. The indexing plunger consists of a pull knob, which is used to pull the indexing pin out of the respective counterpart. The product guarantees a high holding force and a stable and firm fixation as well as uncomplicated handling, which ensures a high level of process reliability during use. Our indexing plungers are particularly robust and durable and are used in machines, for example to secure turning and swivelling devices or for stop positioning. Thanks to their high-quality workmanship, you can be sure that friction-free functionality is guaranteed in practice. Our indexing plungers can withstand the strongest lateral forces. You will find many different designs, dimensions, materials and surfaces in our standard range. We are happy to manufacture other versions on request. The locking bolts with hexagonal collar are available with or without a knob. This cannot be removed. The knob is made of PA 6 thermoplastic, black, matt. The lock nuts must be ordered separately. The screw-in length can be adjusted using spacer rings.
