Self-contained plunger-and-spring device available in many sizes and forces. This standard-length, threaded type has a long stroke and long plunger bearing length for smooth operation. The version shown here has a steel body, and a Delrin plunger nose to prevent marring. Available in thread sizes from #8-32 to 5/8-11 (M6 to M12 in metric), each with a choice of light or heavy spring force. Made in USA. Install and/or adjust from either end. When using the slot at the plunger end to install, use a Plunger Wrench instead of a screwdriver to avoid over-compressing the spring (see Related Products below). A thread-locking element holds the unit securely in place after installation.

Spring plungers can be used to lift parts slightly after machining, for easier unloading.
