Techni-Tool Products Ball and Spring Plungers are devices that enclose a spring in a threaded capsule and provide a means of applying accurate and repeatable spring end forces through a ball or rounded pin. Also known as Spring Loaded Devices, these unique products are essential components in thousands of applications for indexing, positioning, fixturing, locking, ejecting, electrical contacts and many more.

Encapsulating the spring inside a body has several advantages over standard unprotected springs. Installation is quick and easy, side forces can be applied to the assembly and repeatable end forces and extensions are maintained throughout the life of the plunger.

Techni-Tool Products offers Spring Plungers in inch and metric thread sizes, Short Spring Plungers and Ball Plungers in steel and stainless steel materials.
