    Expanding-Diameter Quick-Release Pins

    With a shaft that expands to fill the hole completely, these pins withstand severe vibration and resist pulling. They’re often used to align fixtures during machining as well as open and close molds. Even with repeated insertion and removal, the shaft won’t wear the inside of holes like a retaining ball can. Flip the handle 180° to expand; flip back to contract the shaft and release.
    Corrosion-Resistant Stainless Steel

    High-Strength 17-4 PH Stainless Steel—The strongest stainless steel pins we offer, these are the least likely to deform due to stress and vibration. They resist rust in wet and outdoor environments but won't hold up to the harsh chemicals and acids that 316 stainless steel can.

    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.

    Clamping Quick-Release Pins

    The spring-loaded shaft draws thin sheets of material together and clamps them between the pin’s head and retaining balls. These pins are often used to secure sheet metal while welding to keep the sheets from sliding as you work. Press the button to extend the pin’s shaft and release to retract it up to 5 mm into the head.

    The L-handle takes up less space than a T-handle and swivels to avoid obstacles. Give it a tug to manually retract the nose and make 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.
    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.
