Knob-Style Retractable Spring Plungers
Knurled Knob | With Thread Locker |
Without Thread Locker |
Retract the nose by pulling the knob. These spring plungers have a long nose that provides a large bearing surface to handle side loads.
Knurled knob spring plungers provide a slip-resistant surface for controlled adjustment.
Steel is strong and wear resistant. Zinc-plated steel bodies resist corrosion in wet environments.
316 stainless steel is more corrosion resistant than 18-8 stainless steel and can be used in saltwater environments.
Brass is corrosion resistant in wet environments; brass noses are soft to minimize marring.
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.

Long-Nose Spring Plungers
Install from the nose end without depressing the nose using a driver (sold separately). With a nose that is longer than a ball-nose, these provide a large bearing surface to handle side loads.
Steel is strong and wear resistant. Black-oxide steel bodies resist corrosion in dry environments.
18-8 stainless steel is chemical resistant.
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 element 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.

Extra-Long Hex-Nose Spring Plungers
These spring plungers have a nose that is about three-times longer than standard long hex-nose spring plungers. The extra-long nose provides a large bearing surface to handle side loads. Install from the nose end with a wrench for more torque than slotted long-nose spring plungers. They're made from wear-resistant steel. A nylon locking pellet adds friction to resist loosening.
Black-oxide steel bodies resist corrosion in dry environments.
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.
