Twist-to-Lock Plate-Mount Retractable Spring Plungers
Lock the nose into the retracted position by pulling and rotating the knob. Two mounting holes in the plate allow these plungers to be mounted to a flat surface. They have a long nose that provides a large bearing surface to handle side loads.
Steel is strong and wear resistant.
18-8 stainless steel is chemical resistant and may be mildly magnetic.
Extended nose force is the force required to begin to depress the nose. Compressed nose force is the force required to depress the nose flush with the body. When using a plunger as a detent or stop, a lighter nose force with a shallower hole releases more easily, while a heavier force with a deeper hole holds more securely.

Plate-Mount Retractable Spring Plungers
Two holes in the plate allow these plungers to be mounted to a flat surface. They have a long nose that provides a large bearing surface to handle side loads.
Steel is strong and wear resistant.
18-8 stainless steel is chemical resistant and may be mildly magnetic.
Plungers with zinc alloy plating have countersunk mounting holes.
Extended nose force is the force required to begin to depress the nose. Compressed nose force is the force required to depress the nose flush with the body. When using a plunger as a detent or stop, a lighter nose force with a shallower hole releases more easily, while a heavier force with a deeper hole holds more securely.
