Plungers and pins

Indexing plungers, ball lock pins, push fit spring plungers and more are available straight from stock.


Metric plungers and metric pins are used for positioning parts in fixed positions. Our spring plungers feature a spring with a pin at the end. This creates tension between two objects and keeps them together. Other types of plungers and pins we carry include: long-lok type, ball type, pin type, slotted and hex type, push fit, ball lock and indexing types.

Below, you can see in more detail some of our plungers and pins and the applications they are used in. You can buy these components on our online eStore. Just click the buy button below.
