Vlier SSPH52P Threaded Spring Plunger 10-32 Stainless Steel

Product Description

The VLIER SSPH52P is a threaded spring plunger designed for precise, repeatable positioning and indexing applications in mechanical assemblies. Built with a stainless steel body and nose, it threads into a tapped hole using a 10-32 thread and delivers controlled end force through a spring-loaded plunger mechanism. The plunger projects 1/8 inch beyond the body face and provides an initial end force of 2.9 pounds, a middle end force of 7.0 pounds, and a final end force of 11.1 pounds. A locking element is incorporated into the body to secure the plunger position once set. This part is installed by machinists, toolmakers, and mechanical assembly technicians.

The SSPH52P is suited for use in jigs, fixtures, and precision mechanical assemblies where controlled spring force and positive locking are required. The standard-length plunger configuration and compact 10-32 threaded body make it appropriate for applications with limited space. The stainless steel construction provides corrosion resistance, making it a practical choice for environments where mild chemical exposure or washdown conditions are a concern. It is sold individually and is intended for direct installation into a pre-tapped 10-32 threaded hole.

Key Features

• Stainless steel body and nose for corrosion resistance
• 10-32 threaded body with 3/4 inch thread length for secure mounting
• Locking element included to hold plunger position after adjustment
• 1/8 inch plunger projection for precise positioning contact
• Initial end force of 2.9 pounds and final end force of 11.1 pounds for controlled spring actuation
• Compact hex size of 0.063 inches for installation with standard hex tools

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical assemblies, jigs, and fixtures requiring a 10-32 threaded spring plunger with a standard plunger length configuration.

Installation Notes

Installation requires a pre-tapped 10-32 threaded hole in the mating component. Use a hex key sized to 0.063 inches to thread the plunger body into the hole and to engage the locking element once the desired position is set. Ensure the receiving assembly is secured and de-energized or depressurized as applicable before installing or removing the plunger. Do not over-torque the body, as this may damage the locking element or thread engagement.
