Vlier SSFRSN500 L Handle Spring Plunger 1/2-13

Product Description

The VLIER SSFRSN500 is a stainless steel, non-locking L handle spring plunger designed for indexing, positioning, and light-duty holding applications in industrial assemblies. It features a 1/2-13 thread with a 0.85-inch thread length and a 0.31-inch plunger diameter, delivering an initial end force of 0.5 pounds and a final end force of 2 pounds. The L handle configuration allows manual actuation without additional tools, making it well suited for installations where frequent adjustment or cycling is required. Fabricated from stainless steel, this plunger resists corrosion in wash-down and high-humidity environments.

This spring plunger is used in light industrial, fixture, and machine assembly applications where repeatable positioning is needed. The non-locking plunger design allows the plunger tip to retract freely under axial load, making it appropriate for detent and registration setups. The L handle provides a convenient grip for manual retraction in assemblies where the plunger must be frequently engaged or disengaged by hand without supplemental hardware.

Key Features

• Non-locking plunger allows free axial retraction under load
• L handle design enables tool-free manual actuation
Stainless steel construction provides corrosion resistance in wet or humid environments
• 0.5 lb initial to 2 lb final end force suits light-duty indexing and detent applications
• 1/2-13 thread for standard tapped-hole installation
• Compact body length of 1.5 inches fits space-constrained assemblies

Compatibility

Designed as a standard 1/2-13 threaded spring plunger for use in tapped holes in industrial fixtures, jigs, and machine assemblies requiring non-locking, manual-retract plunger action.

Installation Notes

Installation is typically performed by maintenance technicians or machine builders using a standard wrench on the 0.5-inch hex. Ensure the receiving tapped hole is clean and properly threaded to the 1/2-13 specification before installation. Do not overtighten, as excessive torque can affect plunger travel and end force performance. Verify plunger projection and clearance within the assembly before final seating.
