Flush-Mount Press-Fit Ball-Nose Spring Plungers
The flangeless design allows these spring plungers to mount flush with a surface. Press them into unthreaded holes in soft material such as wood, plastic, and aluminum. Drill a slightly smaller hole for a snug fit.
Steel is strong and wear resistant.
Stainless steel is chemical resistant and may be mildly magnetic. 420 and 440C noses are hard and wear resistant.
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.
