Vlier SPRM10 Locking Pull Ring Plunger M10x1.5

Product Description

The VLIER SPRM10 is a stainless steel locking pull ring plunger designed for precision indexing, positioning, and holding applications in industrial and mechanical assemblies. The body accepts an M10x1.5 thread with a 1.2-inch thread length, making it straightforward to install into tapped holes in fixtures, jigs, tooling plates, and machine frames. The 6 mm plunger diameter delivers a 9.5 mm projection under spring load, with an initial end force of 9 N rising to a final end force of 17.8 N. The locking pull ring allows the plunger to be retracted and held in the disengaged position, freeing both hands during part loading and changeover operations. Overall body length is 43 mm with a 35.5 mm length under the head.

The SPRM10 is suited for light- to medium-duty positioning tasks in manufacturing, tooling, and mechanical assembly environments. Typical install scenarios include fixture plates, drawer stops, locating nests, sliding panels, and adjustable machine guards where a repeatable, low-force detent point is needed. The stainless steel construction makes it appropriate for environments subject to coolant exposure, wash-down conditions, or corrosion concerns. The 25 mm pull ring diameter provides an accessible grip even when surrounding structure limits clearance. Machinists, tool and die makers, and maintenance technicians are the primary installers of this component.

Key Features

• Locking pull ring retracts and holds plunger disengaged for hands-free part loading
• M10x1.5 thread for direct installation into standard tapped holes
• 6 mm plunger diameter with 9.5 mm projection for positive indexing engagement
• Spring end force range of 9 N initial to 17.8 N final provides controlled detent feel
• Stainless steel construction resists corrosion in coolant and wash-down environments
• 25 mm pull ring diameter for accessible actuation in confined spaces

Compatibility

Designed as a direct-install locking pull ring plunger for M10x1.5 tapped holes in industrial fixtures, jigs, tooling plates, and mechanical assemblies requiring a retractable spring plunger with a locking pull ring.

Installation Notes

Installation requires a tapped M10x1.5 hole at the appropriate depth to accommodate the 1.2-inch thread length. De-energize or lock out any machine before installing or servicing spring plungers on moving components. A standard M10 hex wrench or spanner is typically used to torque the body into the tapped hole. Verify plunger projection and ring clearance before finalizing the assembly to ensure full engagement and unobstructed ring pull.
