Vlier SML10AN Threaded Spring Plunger M10 X 1.5 Steel

Product Description

The VLIER SML10AN is a threaded spring plunger designed for precise indexing, positioning, and light-duty detent applications in mechanical assemblies. The unit features an M10 x 1.5 thread with a body length of 0.866 inches and a maximum plunger diameter of 0.157 inches. The plunger delivers an initial end force of 2.02 pounds and a final end force of 7.87 pounds, providing consistent spring-loaded engagement across its 0.118-inch projection. A built-in locking element secures the plunger in the threaded bore, preventing loosening under vibration or repeated cycling. Both the body and nose are constructed from steel for durability in industrial service environments.

This spring plunger is suited for use in jigs, fixtures, tool holders, machine tool slides, and similar mechanical positioning applications where repeatable detent force is required. It threads directly into a standard M10 x 1.5 tapped hole, making it a straightforward drop-in component for new builds or maintenance replacements in manufacturing and industrial maintenance settings. Machinists, toolmakers, and maintenance technicians typically install this type of component during fixture assembly or equipment overhaul.

Key Features

• M10 x 1.5 thread size for standard metric tapped hole installation
• Steel body and steel nose for strength and wear resistance
• Locking element prevents backing out under vibration
• 2.02-pound initial end force and 7.87-pound final end force for controlled detent engagement
• Standard plunger length type with 0.866-inch body length
• 0.118-inch plunger projection for positive indexing contact

Compatibility

Designed for installation in any M10 x 1.5 threaded bore requiring a standard spring plunger with locking element retention.

Installation Notes

Installation requires a properly tapped M10 x 1.5 through or blind hole in the mating component. Use an appropriate hex key or spanner to engage the locking element after threading to the desired depth. De-energize and lock out any associated machinery before servicing fixtures or assemblies containing this plunger. Verify plunger projection and spring force are appropriate for the detent load before finalizing installation.
