Overview
A ball plunger is a spring-loaded ball set in a compact body. The body is pressed into a bore in a fixture or machine part, and the ball snaps into a mating groove to create a repeatable detent - positioning, indexing, or locking a part without tools. SKN Fastener manufactures ball plungers in eight standard sizes from 2 mm to 12 mm.
Available Sizes and Options
Eight standard sizes cover body diameters from 2 mm to 12 mm (2x3 through 12x16). Housings come in SUS303 stainless steel, H65 copper, phosphor bronze, carbon steel, or POM. Custom sizes and materials are manufactured to your drawing under our OEM/ODM service.
