Gibraltar 10624SS Press Fit Ball Plunger 0.312 in Dia

Product Description

The GIBRALTAR 10624SS is a press fit ball plunger designed for positioning, indexing, and light-duty detent applications in mechanical assemblies. The body is stainless steel with a Delrin ball, combining corrosion resistance with low-friction ball action. The body measures 0.312 inches in diameter and 0.688 inches in length. The ball diameter is 0.25 inches with a maximum reach of 0.09 inches. Initial end force is 2 pounds and final end force is 5 pounds. This plunger installs by press fit into a pre-drilled hole, requiring no threads or additional hardware. Machinists, tool-and-die technicians, and assembly professionals typically spec and install this type of component.

This ball plunger suits applications where repeatable positioning or soft detent feedback is needed in jigs, fixtures, tooling plates, and light mechanical assemblies. The stainless steel body resists corrosion in wash-down or moist environments. The Delrin ball reduces friction and wear against mating surfaces. The press fit installation method makes it appropriate for applications where a flush, clean exterior profile is required and threaded installation is not practical. No flange and no locking element keep the profile minimal.

Key Features

• Stainless steel body for corrosion resistance in demanding environments
• Delrin ball provides low-friction, wear-resistant contact
• Press fit installation — no threads required
• 0.09 inches maximum ball reach for controlled detent travel
• 2 pound initial force and 5 pound final force for light-duty positioning
• No flange, no locking element — minimal profile for tight assemblies

Compatibility

Designed as a press fit ball plunger for use in pre-drilled bores requiring a 0.312 inch diameter hole, typical in jigs, fixtures, tooling plates, and general mechanical assemblies.

Installation Notes

Installation requires pressing the plunger body into a properly sized bore using a press or arbor press — do not hammer directly on the ball. Ensure the bore diameter matches the 0.312 inch body diameter for a proper interference fit. Consult assembly drawings and applicable machine safety procedures before installation. Verify the bore depth accommodates the 0.688 inch body length to achieve full seating.
