Vlier PH52 Threaded Spring Plunger 10-32 3/4 in

Product Description

The VLIER PH52 is a standard threaded spring plunger designed to provide repeatable, spring-loaded positioning and indexing in mechanical assemblies. Featuring a 10-32 thread size with a 3/4 inch thread length, this plunger delivers an initial end force of 2.9 pounds and a final end force of 11.1 pounds, making it suitable for light-duty detent and positioning applications. The steel body and steel nose offer durability in industrial environments. Machinists, toolmakers, and mechanical assembly technicians install this type of component where consistent, adjustable spring force is required in a compact threaded form factor.

The PH52 is used in jigs, fixtures, dies, and precision mechanical assemblies where a small-profile spring plunger is needed to locate, hold, or index a component under controlled spring pressure. The 1/8 inch plunger projection and 0.092 inch plunger diameter make this part well suited for tight-tolerance applications where space is limited. It installs directly into a tapped 10-32 hole and requires no locking element, allowing for straightforward adjustment or removal during setup and maintenance.

Key Features

• 10-32 thread size with 3/4 inch thread length for direct installation into standard tapped holes
• Initial end force of 2.9 pounds and final end force of 11.1 pounds for controlled spring-loaded positioning
• Middle end force of 7.0 pounds provides predictable force progression through travel range
• 0.092 inch plunger diameter and 1/8 inch projection suited for compact, tight-tolerance assemblies
• Steel body and steel nose construction for durability in industrial environments
• No locking element - allows easy adjustment and removal without additional tools

Compatibility

Designed as an OEM-style threaded spring plunger replacement for mechanical assemblies requiring a 10-32 threaded, standard-length spring plunger with a steel body and nose.

Installation Notes

Installation is performed by machinists or mechanical technicians using a hex key sized for the 0.063 inch hex drive. Ensure the receiving hole is tapped to 10-32 specification and is clean and free of debris before installation. De-energize or lock out any machinery before servicing or replacing spring plungers in active assemblies. Do not over-torque during installation, as this can damage the thread or affect plunger travel.
