Hex-Drive Long-Nose Spring Plungers
With Thread Locker
Without Thread Locker
Install with a hex key 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.
Steel is strong and wear resistant. Black-oxide steel bodies resist corrosion in dry environments.
18-8 stainless steel is chemical resistant and may be mildly magnetic.
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 nylon 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.
