Gibraltar MKNL-3-G Knob Handle Non-locking Plunger M10x1.5

Product Description

The GIBRALTAR MKNL-3-G is a non-locking knob handle plunger designed for indexing, positioning, and clamping applications in industrial and mechanical assemblies. It features an M10x1.5 threaded shank with a thread length of 0.748 inches and a knurled knob head for tool-free hand adjustment. The spring-loaded plunger delivers an initial end force of 1 pound, ramping to a final end force of 8 pounds, making it suitable for moderate-duty hold and locate tasks. The body measures 0.95 inches in length and the plunger projects 0.236 inches beyond the body face. Machinists, millwrights, and fixture builders typically specify this style of plunger for jigs, fixtures, and panel assemblies.

The MKNL-3-G is suited for use in fabrication fixtures, machine guarding, tooling plates, and equipment panels where repeatable manual positioning is required. The non-locking plunger design allows the plunger to retract under load without a separate release step, which is practical in high-cycle or quick-change setups. Its compact body length and standard metric thread make it a common choice for integration into both OEM equipment builds and field-fabricated assemblies.

Key Features

• Non-locking plunger retracts under load without a separate release mechanism, supporting high-cycle use
• Knurled knob head allows secure tool-free hand adjustment
• M10x1.5 metric thread with 0.748 inch thread length for broad fixture compatibility
• Spring end force range of 1 pound initial to 8 pounds final provides positive positioning resistance
• Plunger projection of 0.236 inches with a maximum plunger diameter of 0.19 inches suits standard locating hole patterns
• Compact 0.95 inch body length fits tight panel and fixture envelopes

Compatibility

Designed as a standard metric M10x1.5 non-locking knob plunger for use in industrial fixtures, tooling plates, machine panels, and positioning assemblies that require a spring-loaded locating or clamping element.

Installation Notes

Installation is typically performed by machinists, toolmakers, or millwrights using standard hand tools to thread the plunger body into a tapped M10x1.5 hole. Ensure the mating hole is cleanly tapped to full depth to prevent binding or cross-threading. Power down and de-energize any associated equipment before servicing or replacing plunger components in live assemblies. Do not exceed the rated final end force by preloading the plunger beyond its specified travel range.
