    Knob-Grip Retractable Spring Plungers

    Image of Product. Front orientation. Contains Annotated. Spring Plungers. Knob-Grip Retractable Spring Plungers.
    With the most versatile handle we offer, these fit in tight spaces while still giving you something to grab. A tug retracts the nose so you can make controlled adjustments. Use these spring plungers for everything from positioning workpieces to changing the height of tables and platforms.
    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.
    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.
    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.

    L-Handle Retractable Spring Plungers

    Image of Product. Front orientation. Contains Annotated. Spring Plungers. 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.

    T-Handle Weld-On Retractable Spring Plungers

    Image of Product. Front orientation. Contains Annotated. Spring Plungers. T-Handle Weld-On Retractable Spring Plungers.
    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 for controlled adjustments. Since they weld in place, these spring plungers have the strongest hold for aligning, securing, and positioning components on heavy machinery. They can do everything from locking attachments on forklifts to holding dies in place on industrial presses. To change your setup, unthread the spring plunger from the old welded-on barrel and thread it into a new one.
    Zinc-Plated Steel Nose—The strongest, most wear-resistant noses, these won't deform from stress and vibration. They withstand occasional exposure to moisture.
    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.
    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.

    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.
    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.
    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.

    Fasten these spring plungers to a flat surface when it's not possible to thread holes. The plate ensures a stable, even base so the spring plunger never shifts out of place. These spring plungers retract manually with a tug of the knob, so you can make controlled adjustments as needed for your job. They're often used for aligning sheet metal parts for cutting, stamping, and welding.
    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.
    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.

    T-Handle Retractable Spring Plungers

    Image of Product. Front orientation. Contains Annotated. Spring Plungers. T-Handle Retractable Spring Plungers.
    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.
    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.
    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-Grip Weld-On Retractable Spring Plungers

    Image of Product. Front orientation. Contains Annotated. Spring Plungers. Ball-Grip Weld-On Retractable Spring Plungers.
    The smooth ball handle is easy to grip and won't catch on other parts. Pull it back to manually retract the nose and make adjustments whenever you need. Since they weld in place, these spring plungers have the strongest hold for aligning, securing, and positioning components on heavy machinery. They can do everything from locking attachments on forklifts and holding dies in place on industrial presses. To change your setup, unthread the spring plunger from the old welded-on barrel and thread it into a new one.
    Zinc-Plated Steel Nose—The strongest, most wear-resistant noses, these won't deform from stress and vibration. They withstand occasional exposure to moisture.
    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.
    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.

    Plungers

    Bushings

    To align two parts with more precision than standard spring plungers, these index plungers have a mating bushing that improves alignment and repeatability. Press-fit the bushing into one part, and install the plunger body through a hole in the other part. The plunger has a notch on the side for locking it in place with a set screw (not included). A quarter turn of the handle retracts the plunger.

    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.
    316 Stainless Steel Nose—Won't corrode from frequent washdowns with harsh cleaners and detergents.
    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.
