Vlier SSBH60N Threaded Ball Plunger 1/2-13 Stainless Steel

Product Description

The VLIER SSBH60N is a threaded ball plunger designed for controlled end-force applications in precision mechanical assemblies. It features a 1/2-13 thread size, a stainless steel body, and a stainless steel ball measuring 0.281 inches in diameter. The body length is 0.75 inches with a maximum ball reach of 0.072 inches. Initial end force is 6 pounds and final end force is 30 pounds, making it suitable for applications requiring repeatable, spring-loaded detent or positioning force. A locking element is included to secure the plunger in place after installation. This part is installed by machinists, maintenance technicians, and mechanical assemblers working on fixtures, tooling, and equipment.

The SSBH60N is used in industrial and manufacturing environments where a compact, spring-loaded positioning device is required. Its stainless steel construction makes it appropriate for environments exposed to moisture or mild corrosives. The controlled end-force range of 6 to 30 pounds suits light-duty indexing, detent positioning, and part retention in jigs, fixtures, and machine assemblies. It is among the smallest and lightest spring-loaded threaded plunger designs available in this thread class, fitting into tight spaces where larger plungers cannot be used.

Key Features

• 1/2-13 thread size for standard threaded bore installation
• Stainless steel body and ball for corrosion resistance
• 0.281 inches ball diameter with 0.072 inches maximum ball reach
• 6 pound initial end force and 30 pound final end force for controlled detent action
• Integrated locking element to hold position after adjustment
• Compact form factor suited for tight-clearance assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit threaded ball plunger for mechanical assemblies, jigs, fixtures, and tooling requiring a 1/2-13 threaded bore and controlled spring end force.

Installation Notes

Installation is performed by machinists or mechanical technicians using standard hand tools compatible with the 1/2-13 thread form. De-energize or lock out any machinery before installing or servicing plungers in active equipment. Use the locking element to secure final position and prevent backing out under vibration. Avoid over-torquing the body, which can damage the locking element or distort the threaded bore.
