Gibraltar 10602SS Ss Press Fit Ball Plunger 0.25in

Product Description

The GIBRALTAR 10602SS is a stainless steel press fit ball plunger designed for positioning, indexing, and light detent applications in mechanical assemblies. The body measures 0.25 inches in diameter and 0.525 inches in length, with a 0.187-inch stainless steel ball that extends up to 0.07 inches at maximum reach. Initial end force is 1.5 pounds, and final end force is 3.5 pounds, making it well suited for light-duty spring-loaded retention tasks. Machinists, tool and die makers, and maintenance technicians install this type of plunger into pre-drilled bores where a press fit eliminates the need for threads or locking elements.

This ball plunger is used in jigs, fixtures, tooling plates, and assembly equipment where repeatable part positioning or light panel retention is required. The press fit body installs directly into a machined hole sized to match the 0.25-inch body diameter, making installation straightforward without tapping. Both the body and ball are stainless steel, which suits applications where corrosion resistance is a priority, such as food processing equipment, wet environments, or cleanroom tooling. This part ships individually and is sold as a single unit.

Compatibility

Designed as a press fit replacement or new-install ball plunger for machined bores requiring a 0.25-inch diameter body in jigs, fixtures, tooling plates, and light mechanical assemblies.

Installation Notes

Installation is performed by machinists or maintenance technicians using a press or mallet to seat the plunger body into a precision-machined bore sized for an interference fit with the 0.25-inch body diameter. Ensure the bore is clean and free of burrs before pressing to avoid damaging the plunger body or distorting the bore. De-energize or lock out any powered equipment before servicing assemblies that contain this plunger. Do not over-drive the plunger past the intended seating depth, as this can compress the internal spring beyond its design range.
