Vlier SSLM12P Spring Plunger M12x1.75 Knurled Knob

Product Description

The VLIER SSLM12P is a spring plunger with a knurled knob handle designed for use in precision positioning, indexing, and holding applications across industrial and mechanical assemblies. It features an M12x1.75 threaded body with a body length of 1.14 inches and a non-locking plunger that delivers an initial end force of 1 pound and a final end force of 10 pounds. The maximum plunger diameter is 0.236 inches with a plunger projection of 0.236 inches. A locking element is included to secure the plunger position after installation. This part is typically installed by maintenance technicians and mechanical assemblers working in production tooling, fixtures, and equipment.

The SSLM12P is suited for applications where repeatable positioning or detent action is required in metal or composite assemblies. The knurled knob allows for hand-adjustment without additional tools, making it appropriate for fixtures, jigs, and machine components that require periodic plunger engagement or disengagement. The M12x1.75 thread fits standard metric tapped holes and is common in industrial machinery and assembly tooling environments.

Key Features

• Non-locking plunger type for smooth, repeatable engagement
• Knurled knob handle allows tool-free hand adjustment
• End force range from 1 pound initial to 10 pounds final for consistent detent resistance
• Locking element included to secure plunger position in the body
• M12x1.75 metric thread for compatibility with standard tapped metric holes
• Plunger diameter tolerance of +0.000 / -0.001 inches for precise fitment

Compatibility

Designed as a direct-fit spring plunger for industrial fixtures, jigs, and mechanical assemblies using standard M12x1.75 metric threaded bores.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped M12x1.75 metric hole using the knurled knob or an appropriate wrench on the shoulder. Ensure the mating bore is clean and free of debris before threading in the component. Engage the locking element after reaching the desired depth to prevent back-out during operation. Power down or de-energize any equipment before servicing or replacing spring plungers in live machinery.
