Vlier SSPHB60 Threaded Ball Plunger 1/2-13 Stainless Steel

Product Description

The VLIER SSPHB60 is a threaded ball plunger designed for controlled end-force applications in mechanical assemblies, fixtures, and tooling. It features a 1/2-13 thread, a stainless steel body with a passivated finish, and a stainless steel ball measuring 0.281 inches in diameter. The body length is 1.05 inches with a maximum ball reach of 0.072 inches. Initial end force is 6 pounds and final end force is 12 pounds. This plunger is installed by machinists, tool and die makers, and mechanical assembly technicians working with positioning, indexing, and detent applications.

The SSPHB60 is suited for use in industrial fixtures, jigs, automation equipment, and precision mechanical assemblies where repeatable, controlled detent force is required. The stainless steel construction and passivated finish make it appropriate for environments where corrosion resistance is a factor, including wet or washdown-exposed assemblies. It is sold individually and installs directly into a threaded bore.

Key Features

• 1/2-13 thread for direct installation into a standard tapped bore
• Stainless steel body and ball with passivated finish for corrosion resistance
• 0.281 inch ball diameter with 0.072 inch maximum ball reach
• 6 pound initial end force and 12 pound final end force for controlled detent action
• No locking element - threaded engagement only
• Compact 1.05 inch body length suits space-constrained assemblies

Compatibility

Designed as a direct-threaded replacement or new-installation ball plunger for any assembly requiring a 1/2-13 threaded bore and controlled end-force detent function.

Installation Notes

Installation requires a properly tapped 1/2-13 threaded hole in the mating component. Use appropriate thread engagement depth to avoid bottoming the plunger. Apply a calibrated torque wrench and thread-locking compound if retention under vibration is needed, following the equipment manufacturer's assembly specifications. Always de-energize and lock out any powered equipment before servicing assemblies containing this plunger.
