Press-Fit Long-Nose Spring Plungers

Press these spring plungers into unthreaded holes in soft material such as wood, plastic, and aluminum. They have a nose that is longer than ball-nose spring plungers to provide a large bearing surface and handle side loads. A flange keeps the plunger from being pushed through a hole when the ball is depressed. Drill a slightly smaller hole for a snug fit.

Steel is strong and wear resistant. Black-oxide steel bodies resist corrosion in dry environments.

18-8 stainless steel is chemical resistant and may be mildly magnetic.

Plastic is chemical resistant and lightweight; acetal noses are extra soft to minimize marring soft surfaces such as aluminum.

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.
