Vlier SSFRN625 Spring Plunger 5/8-11 Stainless Steel

Product Description

The VLIER SSFRN625 is a non-locking, L-handle spring plunger with a 5/8-11 thread size and a stainless steel body and handle assembly. The plunger delivers an initial end force of 1 pound and a final end force of 5 pounds, making it well suited for indexing, positioning, and light-duty locking applications in tooling fixtures, jigs, and machine assemblies. The body measures 3.05 inches in length with a thread length of 1.82 inches and a plunger diameter of 0.38 inches. The L-handle design allows for hand-tightening and adjustment without tools in accessible locations. Licensed trades and industrial maintenance technicians install this type of plunger in production tooling and mechanical assemblies.

This spring plunger is used in manufacturing, tooling, and mechanical assembly environments where repeatable positioning or detent action is required. The non-locking plunger style allows the plunger to retract under load without a separate release mechanism, which suits applications where parts must be indexed quickly. The stainless steel construction resists corrosion and suits environments with moisture exposure or washdown requirements. It installs into a threaded hole in a panel, plate, or housing and is hand-adjusted via the L-handle.

Key Features

• Non-locking plunger type for quick retract under applied load
• 5/8-11 thread size with 1.82 inches of thread length for secure engagement

• L-handle design allows tool-free hand adjustment
• Plunger projection of 1 inch with a 0.38 inch plunger diameter

Compatibility

Designed as a standard-thread spring plunger for installation in any threaded plate, housing, or fixture accepting a 5/8-11 threaded component. Verify thread depth and clearance against the 1.82 inch thread length and 3.05 inch body length before installation.

Installation Notes

Installation requires a properly tapped 5/8-11 threaded hole in the receiving component. Ensure the thread depth accommodates the full thread length to achieve the specified end force. The L-handle allows hand-tightening; use caution not to overtorque the body into the receiving material, particularly in softer substrates. De-energize or lock out any machine or fixture before servicing or replacing spring plungers in automated or powered assemblies.
