Slotted Long-Nose Spring Plungers
Slotted on both ends for installation with a screwdriver. 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. Zinc-plated steel bodies resist corrosion in wet environments. Black-oxide steel bodies resist corrosion in dry 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 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.

Pull-Ring Retractable Spring Plungers
Retract the nose by pulling the ring. The ring allows you to attach these spring plungers to a lanyard to secure them to machinery and prevent accidental drops. They 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.

Pull-Ring Retractable Spring Plungers with Lanyard
Use the lanyard as a tether to secure the spring plunger to machinery and prevent accidental drops. Retract the nose by pulling the ring. 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.
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.
