Locking Bolt

Construction of indexing plungers

Indexing plungers are elements that enable machine parts to be locked in place or indexed. The classic indexing plunger has a grip knob or a pull ring. These knobs or rings are attached to a spring mechanism, when they are pulled a pin in the other end of the plunger is retracted enabling the connection to be quickly and easily released and re-positioned. Indexing plungers guarantee high retaining forces, stable fastenings and easy handling which ensures high process safety during application.
