Vlier SSLM5P Knob Handle Spring Plunger M5x0.8

Product Description

The VLIER SSLM5P is a knob handle spring plunger designed for precise positioning and indexing applications in mechanical assemblies. Featuring an M5x0.8 thread and a non-locking plunger mechanism, this unit delivers an initial end force of 0.5 pounds and a final end force of 3 pounds, making it well suited for light-duty detent and locating tasks. The knurled knob allows for hand-adjustment without tools. The body measures 0.470 inches in length with a thread length of 0.394 inches. Machinists, tool and die makers, and mechanical assembly technicians typically specify and install this type of component in jigs, fixtures, and precision equipment.

The SSLM5P is used in industrial and manufacturing environments where repeatable positioning is required. Typical applications include fixture plates, machine tool slides, enclosure panels, and assembly jigs that require a hand-operable plunger with consistent spring force. The knurled knob head makes it accessible in tight-clearance locations where a wrench or driver cannot be used. Its compact profile and M5 metric thread suit both OEM equipment builds and field retrofits in light industrial settings.

Installation Notes

Install using the appropriate M5 metric tap and thread the plunger body into the prepared hole by hand using the knurled knob. Apply the locking element to the body threads to prevent backing out under vibration. Ensure the mating bore is clean and free of debris before installation to avoid interference with plunger travel. Always verify plunger projection clearance against the mating surface before finalizing the assembly.
