Vlier SSBH58 Threaded Ball Plunger 3/8-16 Stainless Steel

Product Description

The VLIER SSBH58 is a threaded ball plunger designed for controlled end-force applications in mechanical assemblies. It features a 3/8-16 thread, a 0.188-inch stainless steel ball, and a 5/8-inch stainless steel body. The spring-loaded ball delivers an initial end force of 6 pounds and a final end force of 21 pounds, with a maximum ball reach of 0.048 inches. Compact and lightweight, this plunger represents one of the smallest spring-loaded positioning devices available in this thread class. It is installed by maintenance technicians and mechanical assemblers working with precision positioning, indexing, or detent mechanisms.

The SSBH58 is suited for use in light-duty mechanical positioning applications where repeatable, spring-loaded ball detent action is required. Its all-stainless-steel construction makes it appropriate for environments where corrosion resistance matters, such as food-processing equipment, instrumentation panels, and industrial machinery. The 3/8-16 thread allows installation into standard tapped holes without special tooling.

Key Features

• 3/8-16 thread for installation into standard tapped holes
• 0.188-inch stainless steel ball for smooth, repeatable detent action
• Stainless steel body for corrosion resistance in demanding environments
• Initial end force of 6 pounds and final end force of 21 pounds for controlled positioning
• Maximum ball reach of 0.048 inches
• Compact 5/8-inch body length - among the smallest and lightest spring-loaded devices in its class

Compatibility

Designed as a direct-install threaded ball plunger for any application requiring a 3/8-16 tapped hole and spring-loaded ball detent positioning.

Installation Notes

Install into a properly tapped 3/8-16 hole using a standard hex wrench or appropriate driver. Ensure the mating surface or detent recess is clean and free of burrs before installation. Do not overtighten, as excess torque can restrict ball movement or damage the spring mechanism. Verify ball travel and end force are appropriate for the specific positioning application before final assembly.
