Gibraltar MSDKL50-PT-G Locking Knob Plunger M12x1.75

Product Description

The GIBRALTAR MSDKL50-PT-G is a locking knob handle plunger designed for industrial positioning and indexing applications. It features an M12x1.75 thread with a 25mm thread length and a stainless steel body with a black finish. The Delrin knob provides a secure, ergonomic grip while the integrated locking element holds the plunger firmly in the retracted or extended position. Initial end force is 0.56 pounds and final end force is 1.8 pounds, making this unit suitable for light-duty clamping and positioning work. Machine builders, tooling technicians, and fixture fabricators install this type of component during equipment assembly and maintenance.

This plunger is suited for use in precision fixtures, jigs, machine tools, and positioning assemblies where repeatable locking and release cycles are required. The M12x1.75 thread mates with standard metric tapped holes, allowing straightforward integration into new builds or retrofit applications. Its compact body length of 1.2 inches and plunger projection of 0.236 inches fit environments where space constraints are a consideration. Typical installations are found in light industrial, automation, and workholding equipment across manufacturing facilities.

Key Features

• Locking element holds plunger in place without continuous hand pressure
• M12x1.75 metric thread, 25mm thread length for standard metric fitment
• Delrin knob for comfortable, non-slip manual operation
• Stainless steel construction with black finish for corrosion resistance and durability
• Initial end force of 0.56 pounds, final end force of 1.8 pounds
• Compact 1.2-inch body length suits space-restricted assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial fixtures, jigs, and positioning equipment accepting M12x1.75 metric threaded locking plungers.

Installation Notes

Installation is performed by tooling and machine assembly technicians using standard metric hand tools sized to the 0.472-inch hex body. Power down or de-energize any associated equipment before replacing or installing the plunger. Thread engagement should be verified to the full 25mm thread length to ensure secure seating. Do not exceed the rated end force range during operation, as overloading the locking mechanism may cause premature wear.
