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.
18-8 stainless steel is chemical resistant.
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 Hex-Nose Spring Plungers
Fasten from the nose end with a wrench for more torque than slotted long-nose spring plungers. These spring plungers have a nose that is longer than ball-nose spring plungers to provide a large bearing surface and handle side loads. Made from wear-resistant steel, the body has a black-oxide finish to 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 nylon locking pellet 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.

Mounting Bases for Spring Plungers
Mount ball-nose and long-nose spring plungers to fixture surfaces. Insert the plunger into the threaded hole. They're good for horizontal applications. Fasteners are not included.
Steel mounting bases are strong and wear resistant.
18-8 stainless steel mounting bases are chemical resistant and may be mildly magnetic.
