These spring plungers defy gravity by gripping unthreaded holes, even in overhead and vertical applications. They have an O-ring that squeezes against the sides of the hole to keep the plunger firmly in place. The spring-loaded ball compresses when a part presses against it, and then pops out into a notch or groove to hold the part in place. Use these spring plungers to hold parts in vertical conveyor systems and lock attachments on overhead machinery.
Flanged Profile—The flanged body stops the spring plunger from sliding back through the hole when the nose compresses under a strong force. It also acts as a gripping tab so you can pull the plunger out to make adjustments.
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.
