Thread onto machinery or attach a knob or handle to the threaded spindle. The nose is long to provide a large bearing surface to handle side loads.
Spring plungers with a hex nut can be held in place with the nut after threading to your desired depth. The body has a permanent hex nut attached that allows you to hold the spring plunger in place with a wrench.
Steel is strong and wear resistant.
18-8 stainless steel is chemical resistant and may be mildly magnetic.
Spring plungers without thread locker are for use in soft material such as aluminum, in extreme temperatures, and on parts requiring frequent assembly and removal.
Spring plungers with thread locker have a nylon locking patch bonded to the threads that adds friction to resist loosening.
Extended nose force is the force required to begin to depress the nose. Compressed nose force is the force required to depress the nose flush with the body. When using a plunger as a detent or stop, a lighter nose force with a shallower hole releases more easily, while a heavier force with a deeper hole holds more securely.

Add a knob or handle to the threaded shank. Weld these spring plungers in place for a strong permanent hold. They have a long nose that provides a large bearing surface to handle side loads; pull the handle to retract the nose.
