Vlier SML6A Threaded Spring Plunger M6 X 1 Steel

Product Description

The VLIER SML6A is a standard-length threaded spring plunger designed for positioning, indexing, and light-duty detent applications in mechanical assemblies. The body and nose are both machined from steel, providing durability in industrial and trade environments. It threads in on an M6 x 1.00 metric thread with a thread length of 0.787 inches. The spring delivers an initial end force of 1.57 pounds and a final end force of 4.5 pounds, making it suitable for controlled, repeatable engagement. The plunger projects 0.098 inches at full extension with a maximum plunger diameter of 0.106 inches. This part is installed by machinists, maintenance technicians, and mechanical assemblers.

The SML6A fits threaded bores tapped to M6 x 1.00 in panels, fixtures, jigs, tooling plates, and mechanical enclosures. It is commonly used in light industrial equipment, machine tool fixtures, and assembly jigs where a spring-loaded detent or positioning stop is required. The standard-length body at 0.787 inches suits shallow to mid-depth tapped bores. No locking element is included, allowing the plunger to thread in and be adjusted or removed with standard hex tools.

Key Features

• M6 x 1.00 metric thread with 0.787 inch thread length for standard tapped bore installations
• Steel body and steel nose construction for durability in industrial use
• 1.57 pound initial end force and 4.5 pound final end force for light-duty detent and positioning
• Plunger projection of 0.098 inches with maximum plunger diameter of 0.106 inches
• No locking element, allowing straightforward installation and repositioning
• Standard plunger length type for broad fixture and tooling compatibility

Compatibility

Designed as a direct-fit replacement or new installation for threaded bores tapped to M6 x 1.00 metric specification in mechanical fixtures, tooling plates, jigs, and light industrial equipment panels.

Installation Notes

Installation requires a properly tapped M6 x 1.00 through or blind hole. Use a hex key or appropriate driver to thread the plunger to the desired depth. Power down and de-energize any equipment before servicing assemblies that incorporate this component. Do not overtighten, as this can affect spring preload and plunger travel.
