T-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.
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 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.
