Vlier SMPRT6P Spring Plunger M6x1.0 Non-locking Knob

Product Description

The VLIER SMPRT6P is a non-locking spring plunger with a Delrin knob handle, designed for indexing, positioning, and light-duty holding applications in industrial assemblies. Built from stainless steel, it accepts an M6x1.0 thread with a 13mm thread length and delivers an initial end force of 0.11 pounds and a final end force of 0.34 pounds. The plunger projects 0.118 inches (3mm) at maximum extension, with a plunger length of 0.98 inches. Machinists, toolmakers, and assembly technicians install this type of component into threaded holes in jigs, fixtures, and machine components where repeatable detent or positioning action is required.

This spring plunger is suited for light industrial positioning tasks in ferrous and non-ferrous assemblies. The knob-style handle allows manual adjustment by hand without tooling. The stainless steel body resists corrosion in wash-down or humid environments. Typical applications include tooling fixtures, slide detents, and panel positioning assemblies where low end-force requirements and a compact form factor are priorities. The Delrin knob provides a non-marring grip surface appropriate for precision setups.

Key Features

• M6x1.0 thread with 13mm thread length for standard metric tapped holes
• Non-locking plunger design allows free retraction without a release mechanism
• Delrin knob handle enables hand adjustment without additional tools
• Initial end force of 0.11 pounds, final end force of 0.34 pounds for light-duty indexing
• Stainless steel body construction for corrosion resistance
• Locking element included to secure the plunger body in the tapped hole after installation

Compatibility

Designed as a direct-fit replacement or new installation for M6x1.0 threaded holes in jigs, fixtures, and light industrial assemblies requiring a non-locking knob-handle spring plunger with a 13mm thread length.

Installation Notes

Installation is performed by toolmakers or precision assembly technicians using standard metric hand tools. Thread the plunger body into a properly tapped M6x1.0 hole and tighten the locking element to secure position. Power down or de-energize any associated machine or assembly before installation. Do not exceed the rated end force by substituting a stiffer spring or over-torquing the locking element, as this may damage the Delrin knob or the plunger mechanism.
