Vlier SSFRSN375 L Handle Spring Plunger 3/8-16

Product Description

The VLIER SSFRSN375 is a stainless steel, L-handle spring plunger designed for precise, repeatable positioning and indexing in industrial and mechanical assemblies. It features a 3/8-16 thread with a 0.62-inch thread length and a 0.25-inch diameter plunger that delivers an initial end force of 0.25 pounds and a final end force of 1.25 pounds. The non-locking design allows fast manual operation using the integrated L-shaped handle, making it well suited for applications that require frequent adjustment or removal. The stainless steel construction resists corrosion and is appropriate for demanding environments.

This spring plunger is used in fixture building, jig positioning, tooling plates, and machine assembly where repeatable stop or detent action is needed. The L-handle drive provides a convenient manual grip for installation and removal without additional tools in many setups. With a compact body length of 1.13 inches and a plunger projection of 0.30 inches, it fits into tight assemblies where space is limited. It is typically installed by machine builders, tool and die technicians, and maintenance mechanics working with positioning fixtures or automation equipment.

Key Features

• Stainless steel construction for corrosion resistance in harsh or washdown environments
• Non-locking plunger design allows rapid manual adjustment without tools
• Integrated L-handle with 0.56-inch handle length for easy hand tightening and removal
• Initial end force of 0.25 pounds and final end force of 1.25 pounds for consistent indexing performance
• Compact 1.13-inch body length and 0.30-inch plunger projection suits tight fixture assemblies
• Standard 3/8-16 thread for broad compatibility with common tapped holes in tooling plates and fixtures

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial fixtures, jigs, and positioning assemblies that accept a 3/8-16 threaded spring plunger with an L-handle drive style.

Installation Notes

Installation is performed by threading the plunger body into a tapped 3/8-16 hole by hand or with a wrench applied to the hex, then tightening to the appropriate torque for the application per the fixture design specification. Always verify the assembly is de-energized and any moving components are locked out before installing or removing positioning hardware. Inspect the plunger and spring for wear during scheduled maintenance intervals. Follow applicable machine safety standards for the equipment in which this component is installed.
