Gibraltar SSWN10-4BH-PT-G Threaded Ball Plunger 1/4-20

Product Description

The GIBRALTAR SSWN10-4BH-PT-G is a threaded ball plunger designed for indexed positioning and detent applications in mechanical assemblies. The body is machined from stainless steel with a 1/4-20 thread, a 0.531-inch body length, and a nylon ball measuring 0.125 inches in diameter. Maximum ball reach is 0.035 inches. Initial end force is 4 pounds and final end force is 12 pounds, providing a firm, repeatable hold when engaged. A locking element is built into the body to secure the plunger at a set depth once installed. This part is typically installed by machinists, maintenance technicians, and mechanical assembly professionals.

Threaded ball plungers of this type are used in jigs, fixtures, tooling plates, machine slides, and light industrial equipment wherever a spring-loaded detent or positioning stop is required. The stainless steel body resists corrosion in washdown or high-humidity environments. The nylon ball reduces marring on softer mating surfaces and suits applications where metal-to-metal contact is undesirable. The 1/4-20 thread allows installation into standard tapped holes common across a wide range of fixture and tooling designs.

Key Features

• 1/4-20 threaded stainless steel body for corrosion resistance and secure installation
• Nylon ball construction minimizes surface marring on contact surfaces
• 0.125-inch ball diameter with 0.035-inch maximum ball reach
• 4-pound initial end force and 12-pound final end force for firm detent engagement
• Integrated locking element allows depth adjustment to be fixed after positioning
• Color code: Purple for quick field identification of force range

Compatibility

Designed as a standard 1/4-20 threaded ball plunger for use in tapped holes in jigs, fixtures, tooling plates, and mechanical assemblies requiring spring-loaded detent or positioning functionality.

Installation Notes

Installation requires a pre-tapped 1/4-20 hole in the mating component. Use an appropriate hex key or spanner to thread the plunger body to the desired depth before engaging the locking element to fix the position. Ensure the mating surface travel path is clear of burrs or debris that could damage the nylon ball. Disengage or isolate any moving machine components before servicing or replacing this part.
