Align, position, and lock moving parts for most machining and assembly tasks. These spring plungers have a spring-loaded ball that compresses when a part presses against it, and then pops out into a notch or groove to hold the part in place. Unlike long-nose spring plungers, the ball rolls easily in and out of position, so they're a great fit for applications that require consistent, smooth movement, such as positioning parts in an assembly line and aligning fixtures and jigs when cutting or drilling.

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.

The L-handle on these spring plungers takes up less space than a T-handle and swivels to avoid obstacles. Pull it back to manually retract the nose and position, align, and lock components as needed for your job.

Install spring plungers from the nose end without depressing the nose.

With the widest grip, T-handles give you the most leverage of all our handles and are the easiest to grab with gloved or slippery hands. A tug manually retracts the nose so you can do everything from latching heavy, frequently-accessed doors to locking large cutting blades in place.

With rounded edges and polished surfaces, these spring plungers are free of nooks and crannies where dirt, water, and bacteria could collect. The seal on the base keeps contaminants off the threads and is bright blue, so you can easily spot broken pieces that fall into your line. A tug of the knob manually retracts the nose so you can do everything from positioning containers on an assembly line to locking mixing blades in place. Spring plungers are FDA compliant for direct contact with food.

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.

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.
