Press-Fit Ball-Nose Spring Plungers

Flanged Profile |
When you can't tap threads in your mounting surface, push these spring plungers into unthreaded holes. They work well in wood, plastic, and other soft materials that might crack if you try to cut threads. 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.
For a snug fit, use an arbor press to install these spring plungers in a slightly smaller hole than the body diameter.
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.
420 Stainless Steel Nose—Highly wear resistant, the nose grinds against hard metal surfaces without denting or scratching. However, 420 stainless steel is not quite as corrosion resistant as 316 stainless steel.
Acetal Nose—The best plastic for damp and wet environments, acetal won't swell or lose strength if exposed to moisture. These noses are extra soft to avoid scratching delicate surfaces. They are best for use on soft materials, such as aluminum.
Smooth Body—These spring plungers slide effortlessly into unthreaded holes, but don't grip quite as firmly as those with a knurled body.
