Twist-to-Lock Knob-Style Retractable Spring Plungers
 Smooth Knob With Hex Nut |  Without Thread Locker |
 With Thread Locker |
Lock the nose into the retracted position by pulling the knob and rotating it 90°. These spring plungers have a long nose that provides a large bearing surface to handle side loads.
Smooth knob spring plungers with a hex nut can be held in place with the nut after threading to your desired depth.
Steel is strong and wear resistant. Black-oxide steel bodies resist corrosion in dry environments.
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 locking patch 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.
