Vlier SSM12AN Threaded Spring Plunger M12 X 1.75 Ss

Product Description

The VLIER SSM12AN is a threaded spring plunger with an M12 x 1.75 thread size and a standard stainless steel body. It is designed to provide controlled, repeatable positioning force in mechanical assemblies, fixtures, jigs, and tooling applications. The plunger delivers an initial end force of 10.12 pounds and a final end force of 24.73 pounds, making it suitable for applications that require firm, predictable detent or retention action. The stainless steel body and nose construction offer corrosion resistance for demanding environments. A locking element is included to secure the plunger in the threaded bore after installation and prevent backout under vibration or repeated cycling.

The SSM12AN is used in industrial, mechanical, and trade applications where a threaded plunger is required to index, locate, or retain a moving component. Typical installations include machine fixtures, assembly tooling, enclosure latches, and precision positioning devices. The M12 x 1.75 thread size fits standard metric-tapped bores. Its compact body length of 1.102 inches and plunger projection of 0.157 inches make it appropriate for space-constrained installations. Machinists, millwrights, and industrial maintenance technicians are the primary installers of this type of component.

Key Features

• M12 x 1.75 thread for standard metric bore installations
• Stainless steel body and nose for corrosion resistance in wet or harsh environments
• Locking element prevents plunger backout under vibration or cyclic loads
• Initial end force of 10.12 pounds and final end force of 24.73 pounds for reliable detent action
• Standard plunger length of 1.102 inches with a maximum plunger diameter of 0.236 inches
• Plunger projection of 0.157 inches for controlled engagement depth

Compatibility

Designed as a direct-fit threaded spring plunger for any application requiring an M12 x 1.75 metric-threaded bore with a standard-length stainless steel plunger body.

Installation Notes

Install using a hex key or spanner appropriate for the body style into a clean, properly tapped M12 x 1.75 metric bore. Engage the locking element per the manufacturer procedure to secure the body against rotation after final positioning. Ensure the mating bore depth accommodates the full body length of 1.102 inches without bottoming out. De-energize or lock out any associated machinery before servicing or replacing spring plungers in active assemblies.
