High-Torque Ball-Nose Spring Plunger

Manufacturer part: 5901A17

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.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.
