Lock the nose into the retracted position by pulling the ring and rotating it 90°. 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.
