Hand retractable spring plungers are precision machined from solid bar stock. The retractable plunger is hardened for greater side load strength in the extended position and is slightly tapered for easy alignment. All handle styles are easy to grip for fast, one-handed operation. With a 90° turn of the handle, the locking types will lock the plunger in the retracted position.

Hand retractable plungers have many industrial, medical and consumer applications and are commonly used as indexing, positioning and fastening components. Their quick disconnect and positive locking features are ideal for many applications.
