Knurled Press-Fit Ball Plungers

Knurled Press-Fit Ball Plungers are press-in spring loaded devices for securing, indexing, locating and positioning in wood, soft plastic or aluminum when a threaded ball plunger is impractical or threaded adjustment is not required. Choose a nylon ball for non-marring contact or a steel ball for a hardened contact point. Bodies are available in steel or stainless steel, with stainless steel providing improved corrosion resistance and high temperature capability. Not available in metric.
