Vlier SLM12P Non-locking Knob Handle Plunger M12x1.75

Product Description

The VLIER SLM12P is a non-locking spring plunger with a knurled knob handle, designed for indexing, positioning, and locating applications in industrial and mechanical assemblies. It features an M12x1.75 threaded body with a 0.905-inch thread length and a 0.236-inch maximum plunger diameter. The plunger delivers 1 pound of initial end force rising to 10 pounds of final end force, making it well suited for light-duty detent and registration tasks. A locking element is included in the body. Machinists, toolmakers, and mechanical assemblers typically install this type of component in fixtures, jigs, and production equipment.

The SLM12P is used in industrial fixtures, assembly tooling, and machine components where repeatable plunger engagement is required. Its compact body length of 1.14 inches and knurled knob allow hand adjustment without additional tooling, making it practical for frequently accessed positions in production or maintenance environments. The non-locking plunger type allows the nose to retract smoothly under load without requiring deliberate override.

Key Features

• Non-locking plunger design allows smooth retraction under applied load
• Knurled knob handle enables hand adjustment without tools
• M12x1.75 thread for straightforward installation in standard threaded bores
• 1 pound initial to 10 pounds final end force for light-duty detent applications
• Locking element included in body to secure set position
• Plunger projection of 0.236 inches provides consistent indexing engagement depth

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial fixtures, jigs, and assemblies requiring an M12x1.75 threaded spring plunger with a knob handle.

Installation Notes

Installation is performed by machinists or mechanical assemblers using a standard threaded bore sized for M12x1.75. Ensure the receiving bore is clean and free of debris before threading in the body. Engage the locking element only after the plunger is set to the desired position. Do not overtighten, as this can affect plunger travel and spring force consistency.
