Gibraltar 10604 Steel Press Fit Ball Plunger

Product Description

The GIBRALTAR 10604 is a press fit ball plunger designed for use in tooling, fixtures, jigs, and mechanical assemblies where spring-loaded detent or positioning action is required. The body measures 0.375 inches in diameter and 0.864 inches in length, with a stainless steel ball measuring 0.438 inches in diameter and a maximum ball reach of 0.11 inches. Initial end force is 2.5 pounds and final end force is 7 pounds, providing reliable spring tension for light-duty indexing and positioning applications. The steel body features a black finish with a purple color code for quick identification. Machinists, tool and die makers, and mechanical assembly technicians typically install this component.

This ball plunger is suited for use in precision fixtures, machine tool components, and mechanical assemblies where a press fit installation is required. The press fit design eliminates the need for threads, allowing direct installation into a bored hole. The no-flange, no-locking-element configuration keeps the installed profile low and the installation straightforward. It is appropriate for both light industrial and shop floor applications where repeatable detent positioning or part retention is needed.

Compatibility

Designed as an OEM-style replacement or standard component for tooling fixtures, jigs, and mechanical assemblies requiring a press fit ball plunger with a 0.375 inch body diameter.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using a press or arbor press to seat the body into a properly sized bored hole. The receiving hole diameter and depth should be machined to the manufacturer's specified tolerances before installation to ensure correct fit and spring function. De-energize or lock out any powered equipment before servicing assemblies that contain this component. Do not use a hammer directly on the ball or body, as this can damage the spring mechanism or deform the body.
