Gibraltar 10104-G Threaded Ball Plunger 1/4-20 Ss Locking

Product Description

The GIBRALTAR 10104-G is a threaded ball plunger designed for use in positioning, locating, and indexing applications where a spring-loaded ball provides controlled detent force. The body and ball are both stainless steel construction, giving this plunger strong corrosion resistance in demanding environments. The 1/4-20 thread allows direct installation into a tapped hole without additional hardware. A locking element is incorporated into the body to prevent the plunger from backing out under vibration or repeated cycling. Initial end force is 2 pounds, with a final end force of 4 pounds as the ball is fully depressed.

This ball plunger is suited for light industrial, tooling, fixture, and machine assembly applications where repeatable part positioning or panel retention is required. The stainless steel construction makes it appropriate for environments where carbon steel hardware would corrode, including food processing equipment, medical devices, marine fixtures, and outdoor assemblies. It is typically installed by machinists, toolmakers, or maintenance technicians working on jigs, fixtures, or OEM equipment assemblies.

Key Features

• 1/4-20 threaded body for direct installation into a standard tapped hole
• Stainless steel body and ball for corrosion resistance
• Locking element prevents backing out under vibration
• 2 pound initial end force and 4 pound final end force for controlled detent action
• 0.125 inch ball diameter with 0.035 inch maximum ball reach
• Compact 0.5313 inch body length suits tight clearance applications

Compatibility

Designed as an OEM-style component for use in any application requiring a 1/4-20 threaded ball plunger with stainless steel construction and a locking element.

Installation Notes

Installation requires a clean, properly tapped 1/4-20 hole in the mating component. The locking element secures the plunger body in place without the need for thread-locking compound, though the element should be fully engaged before placing the assembly into service. Avoid over-torquing during installation, as excessive force can damage the locking element or distort the body. No special certifications are required for installation, though standard machining and assembly practices apply.
