Hand Retractable Spring Plunger SKNL-6-316 Non-Locking Hand Retractable Knurled Handle Spring Plungers without Nylon Patch

S&w spring and 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. Most installations can be done with a screwdriver, but care must be taken since the body is hollow and does not have the strength of a bolt or screw.
