Vlier SSLM6 Knob Handle Spring Plunger M6x1.0

Product Description

The VLIER SSLM6 is a non-locking, knob-style spring plunger designed for precision indexing, positioning, and light-duty detent applications in mechanical assemblies. It uses an M6x1.0 thread with a 0.512 inches thread length and delivers an initial end force of 1 pound, ramping to a final end force of 4 pounds. The knurled knob head allows for manual adjustment without tools, making it well-suited for fixtures, jigs, and assemblies where the plunger position needs to be set and reset by hand. Licensed technicians and mechanical assemblers install this type of component in production tooling, machine guarding, and panel assemblies.

The SSLM6 fits into any threaded bore or housing machined to accept an M6x1.0 thread. Its compact body length of 0.630 inches keeps the installed footprint small, making it appropriate for tight-clearance assemblies. The non-locking design allows the plunger to retract freely under load, which is the correct choice for spring-return or soft-stop indexing scenarios. Typical applications include light manufacturing equipment, inspection fixtures, panel latches, and mechanical stops where repeatable low-force positioning is required.

Key Features

• Non-locking plunger retracts freely under applied load for spring-return detent function
• Knurled knob head allows hand adjustment without tools
• M6x1.0 thread with 0.512 inches thread engagement length
• End force range: 1 pound initial to 4 pounds final
• Maximum plunger diameter of 0.118 inches with a tight tolerance of +0.000 / -0.001 inches
• Compact 0.630 inches body length for tight-clearance installations

Compatibility

Designed as an OEM-style replacement or direct-fit component for any assembly using an M6x1.0 threaded spring plunger with a knob-style handle in a non-locking configuration.

Installation Notes

Installation requires a properly tapped M6x1.0 threaded bore in the mating component. Thread engagement should match the 0.512 inches length under head to ensure the plunger seats flush and operates correctly. Confirm the bore depth accommodates the full plunger projection of 0.118 inches before assembly. Do not overtighten the knob body, as this can bind the plunger mechanism and reduce spring travel.
