Vlier SSL375 Knob Handle Spring Plunger 3/8-16

Product Description

The VLIER SSL375 is a knob handle spring plunger with a 3/8-16 thread size and a 0.75 inch thread length. It is used to locate, position, or hold components in assemblies where repeatable detent action is required. The plunger is non-locking and constructed from stainless steel for corrosion resistance in demanding environments. Initial end force is 1 pound and final end force is 8 pounds, giving technicians and machinists a defined force range for positioning applications. The knurled knob provides a secure grip for manual adjustment without tools. Maintenance technicians, tool and die professionals, and industrial assembly workers are the typical installers.

The SSL375 is suited for use in industrial machinery, fixtures, jigs, and tooling assemblies where a threaded spring plunger with a hand-adjustable knob is needed. The 0.94 inch body length and 0.185 inch maximum plunger diameter make this a compact plunger appropriate for tight-clearance installations. It fits standard 3/8-16 threaded holes and is well suited for applications requiring stainless steel construction, such as food processing equipment, wet environments, or corrosion-sensitive machinery.

Key Features

Compatibility

Designed as a direct-fit replacement or new installation for standard 3/8-16 threaded spring plunger applications in industrial fixtures, jigs, and positioning assemblies.

Installation Notes

Installation is performed by threading the SSL375 into a prepared 3/8-16 tapped hole by hand or with a wrench applied to the knob body. Ensure the mating bore is clean and free of debris before installation. Verify plunger projection and end force are appropriate for the detent or positioning load required before finalizing installation. No power sources need to be isolated, but machinery should be de-energized and locked out per applicable safety procedures before servicing assemblies.
