Techni-Tool Products Inc.



Spring and Press-Fit Ball 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 nose. Also known as Spring Loaded Devices (SLDs), the unique features of ball and spring plungers make them essential components in thousands of applications for indexing, positioning, fixturing, latching, locking, ejecting, electrical contacts and many others.


These plungers have different installation methods including hex socket, slotted drive and top slot for blind-holes and have light, standard, or heavy end forces available to them. Types of ball & spring plunges include inch ball nose plungers, metric ball nose plungers, slotted drive with lock plungers, hex drive lock plungers, press fit body plungers, press fit body with collar plungers, short body stainless steel nose plungers, short body heavy pressure plungers, and many more.


Encapsulating the spring inside the body has several advantages over standard, unprotected springs: installation is fast and easy, side forces can be applied to the assembly and repeatable end forces and extension are maintained throughout the life of the ball nose spring plunger.
