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.

Acetal Nose—The best plastic for damp and wet environments, acetal won't swell or lose strength if exposed to moisture. These noses are extra soft to avoid scratching delicate surfaces. They are best for use on soft materials, such as aluminum.

L-Handle Retractable Spring Plungers

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.

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.

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.

Twist-to-Lock—Free up both hands to adjust your workpiece or switch out parts without the plunger springing back and getting in the way. Pull back the handle and twist to lock the nose in its retracted position.

Ball-Nose Spring Plungers

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.

440C Stainless Steel Nose—The strongest, most wear-resistant stainless steel noses, these grind against hard metal surfaces without denting or scratching. However, they are not as corrosion resistant as 316 stainless steel.

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.

Low-Profile Knob-Grip Retractable Spring Plungers

With the sleekest knob we offer, these fit in areas with low clearance, such as in between conveyors. They tighten with a hex key for installation in cramped spots where your fingers might not reach. Tug the knob back to manually retract the nose so you can position, align, and lock components as needed for your job.
