Vlier PH48B Threaded Spring Plunger 6-32 Steel Body

Product Description

The VLIER PH48B is a threaded spring plunger designed to provide controlled, spring-loaded positioning and indexing in precision assemblies. It features a 6-32 thread size with a 17/32 inch thread length and a steel body and nose. The plunger diameter ranges from 0.044 to 0.045 inches, with a 1/16 inch projection beyond the mounting surface. Initial end force is 1 pound and final end force is 1.6 pounds, making this a light-duty plunger suited for fine-tolerance applications. Machinists, toolmakers, and assembly technicians install this type of component in jigs, fixtures, and light-duty positioning mechanisms.

This spring plunger is intended for use in precision machined components, tool and die assemblies, fixtures, and similar industrial applications where repeatable detent or positioning force is required. The 6-32 thread allows installation into standard tapped holes of that size. Its compact body length of 17/32 inch suits confined spaces in machined housings or fixture plates. Standard plunger length type indicates a conventional non-extended body configuration. This part ships in a package quantity of one.

Key Features

• 6-32 thread size with 17/32 inch body and thread length for compact installation
• Steel body and steel nose for durability in industrial environments
• 1/16 inch plunger projection suitable for light detent and indexing applications
• Initial end force of 1 pound and final end force of 1.6 pounds for controlled spring resistance
• Plunger diameter of 0.044 to 0.045 inches for fine-tolerance fitment
• No locking element, allowing straightforward threaded installation and removal

Compatibility

Designed as an OEM-style threaded spring plunger for use in standard 6-32 tapped holes in precision machined assemblies, jigs, fixtures, and industrial positioning equipment.

Installation Notes

Installation is performed by machinists or assembly technicians using a hex wrench sized to the 0.063 inch hex. Ensure the receiving hole is properly tapped to 6-32 specifications and free of debris before threading in the plunger. Do not overtighten, as this can damage the plunger mechanism or distort the body. No locking element is included, so thread-locking compound may be applied if retention under vibration is required.
