Long-Nose Spring Plungers
 |  |  |
Lock heavy moving parts securely in place. Often used in indexing applications, these have a longer nose than ball-nose spring plungers to withstand greater side forces without disengaging. The nose compresses when a part presses against it, and then pops out into deep notches or grooves for a strong hold.
Spring plungers are available with or without a threadlocker. Those with a threadlocker won't wiggle loose from vibration. Spring plungers without a threadlocker are easier to remove.
Steel Nose—The strongest, most wear-resistant noses, these won't deform from stress and vibration. Steel is best for dry environments, however, since moisture will cause it to rust.
18-8 Stainless Steel Nose—The choice for wet and outdoor environments, 18-8 stainless steel resists rusting. It's strong enough for most jobs, but won't withstand stress and vibration as well as steel.
316 Stainless Steel Nose—With the best corrosion resistance of all, 316 stainless steel stands up to harsh weather, salt water, and chemicals. The nose is strong enough for most jobs, but won't withstand stress and vibration as well as steel.
Brass Nose—Similar to 18-8 stainless steel, brass is corrosion resistant enough to stand up to wet environments. Since brass is softer than other metals, these noses are less likely to dent surfaces, however, they could deform under high stress.
Extended Nose Force—This is the amount of force needed to start depressing the nose.
Compressed Nose Force—This is the amount of force needed to fully depress the nose into the plunger body, so it releases from a hole, notch, or surface. A lighter compressed nose force with a shallower hole releases more easily, while a heavier compressed nose force with a deeper hole holds more securely.

Long-Nose Spring Plungers For Ejecting
 |
 |
Punch large parts free from presses or dies with a nose that’s three times longer than others. These spring plungers also have a long spring that doesn’t need to compress as far to retract the nose, so it can handle high speed, repetitive ejecting jobs without wearing down.
Steel Nose—The strongest, most wear-resistant noses, these won't deform from stress and vibration. Steel is best for dry environments, however, since moisture will cause it to rust.
Extended Nose Force—This is the amount of force needed to start depressing the nose.
Compressed Nose Force—This is the amount of force needed to fully depress the nose into the plunger body, so it releases from a hole, notch, or surface. A lighter compressed nose force with a shallower hole releases more easily, while a heavier compressed nose force with a deeper hole holds more securely.
Ring-Grip Retractable Spring Plungers

Loop a lanyard through the ring to secure these spring plungers to machinery and prevent accidental drops. Pull the ring back to manually retract the nose and position, align, and lock components as needed for your job.
