Vlier H67 Threaded Spring Plunger 1/8 Thread

Product Description

The VLIER H67 is a standard threaded spring plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. The steel body and steel nose deliver consistent spring force across the full compression stroke, with an initial end force of 4 pounds and a final end force of 31 pounds. The 1/8-inch thread size and 2-13/32 inch body length make this a compact, drop-in solution for tooling fixtures, jigs, and production machinery where repeatable positioning is required. Installation is straightforward with a 1/2-inch hex drive for torquing into threaded bores.

This spring plunger fits applications in industrial tooling, fixture plates, assembly jigs, and general mechanical positioning systems. The 1/2-inch projection allows adequate nose travel to engage mating detent features reliably. The 1/8-inch thread size suits light-duty mechanical assemblies where a small-profile fastener thread is specified. Machinists, tool and die makers, and maintenance technicians working on production equipment are the primary installers of this component.

Key Features

• Steel body and steel nose for durability in industrial environments
• Initial end force of 4 pounds, final end force of 31 pounds, middle end force of 17.5 pounds
• 1/8-inch thread size with 2-13/32 inch thread length for standard threaded bore installation
• 1/2-inch plunger projection for reliable detent engagement
• 1/2-inch hex drive for precise installation with a standard wrench
• No locking element - free-spinning nose for smooth engagement and release

Compatibility

Designed as a standard OEM-style threaded spring plunger for use in mechanical assemblies, tooling fixtures, and jigs requiring a 1/8-inch threaded bore and a 1/2-inch projection nose.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard hex wrench matched to the 1/2-inch hex drive. Ensure the mating bore is clean and threaded to the correct specification before installation. Do not overtighten, as excessive torque can bind the internal spring mechanism and affect force output. Verify plunger projection and end force values are appropriate for the detent load before assembly.
