    18-8 Stainless Steel—The choice for wet and outdoor environments, these pins resist rusting. They are strong enough to join most components but won't withstand stress and vibration as well as steel.

    Add-a-Handle Retractable Spring Plungers

    Customize these spring plungers with a handle (not included) that's the size, shape, texture, and color you want. Retractable spring plungers give you the control to position, align, and lock components as needed for your job.
    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.
    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.

    Add-a-Handle Weld-On Retractable Spring Plungers

    Image of Product. Front orientation. Contains Annotated. Spring Plungers. Add-a-Handle Weld-On Retractable Spring Plungers.
    Thread on whichever handle (not included) springs to mind to control when and how you retract the nose. 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.
