Twist-to-Lock L-Handle Retractable Spring Plungers
 |  With Thread Locker |
 Without Thread Locker |
Lock the nose into the retracted position by pulling the handle and rotating it 90°. These spring plungers have a long nose that provides a large bearing surface to handle side loads.
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.
Plastic is chemical resistant and lightweight; acetal noses are extra soft to minimize marring soft surfaces such as aluminum.
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.

L-Handle Retractable Spring Plungers
 | With Thread Locker |
Without Thread Locker |
Retract the nose by pulling the handle. These spring plungers have a long nose that provides a large bearing surface to handle side loads.
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.

Low-Profile Knob-Style Retractable Spring Plungers with Hex Drive
 | With Thread Locker |
Without Thread Locker |
Install by hand or with a hex key in low-clearance applications. Retract the nose by pulling the knob. These spring plungers have a long nose that provides a large bearing surface to handle side loads.
Steel is strong and wear resistant.
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.

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.

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.
Zinc-plated steel bodies resist corrosion in wet 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. 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.

Hex-Drive Ball-Nose Spring Plungers
Install with a hex key for more torque than slotted ball-nose spring plungers. They have a ball nose that rolls to minimize wear and allow parts to move in and out of position. Made from 440C stainless steel, the nose is hard, wear resistant, and mildly chemical resistant.
Steel bodies are strong and wear resistant. They have a black-oxide finish to resist corrosion in dry environments.
18-8 stainless steel bodies are 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 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.
