Description
Spring Plungers
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 has a steel body and a hardened steel plunger nose. 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. A thread-locking element holds the unit securely in place after installation.
Application Information
Spring plungers can be used to lift parts slightly after machining, for easier unloading.
