Gibraltar MSDKN25-PT-G Knob Handle Plunger M6x1.0

Product Description

The GIBRALTAR MSDKN25-PT-G is a non-locking knob handle plunger with an M6x1.0 thread and a Delrin knob head. It is a spring-loaded positioning component used in industrial fixtures, jigs, tooling setups, and machine panels where a hand-operated, tool-free plunger is needed to locate, index, or retain a moving part. The plunger body measures 0.63 inches in length with a maximum plunger diameter of 0.118 inches and a plunger projection of 0.118 inches. Initial end force is 0.11 pounds, rising to a final end force of 0.34 pounds. A locking element is included. Installation requires no special tooling beyond standard hex wrenches.

This plunger is suited for light-duty indexing and positioning applications in manufacturing, assembly, and mechanical fixture work. Typical installations include panel-mounted locating mechanisms, sliding subassemblies, and lightweight door or gate latching on machinery and workholding equipment. The compact body size and low spring force make it appropriate for applications where minimal actuation effort is required and where a Delrin knob provides a comfortable hand-operated interface without tools. The 13 mm thread length allows secure engagement in standard threaded inserts or tapped holes in metal or plastic housings.

Key Features

• Non-locking plunger design allows free hand operation without a separate release step
• Delrin knob head provides a smooth, durable grip surface resistant to wear and chemicals
• M6x1.0 thread with 13 mm thread length fits standard metric tapped holes
• Low spring force profile: 0.11 lb initial to 0.34 lb final end force for light-duty indexing
• Locking element included to secure the plunger body in position after installation
• Compact 0.63-inch body length suits tight panel and fixture clearances

Compatibility

Designed for use in any application requiring an M6x1.0 threaded non-locking knob plunger in metal or plastic panels, fixtures, or housings with sufficient thread engagement for a 13 mm thread length.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped M6x1.0 hole using the integrated hex flats and a standard 6 mm hex wrench. Tighten the locking element against the mounting surface to fix the body in place and prevent rotation during use. Do not overtighten, as the Delrin knob and plunger components are not rated for high-torque installation. Ensure the plunger bore is clean and free of debris before seating to avoid binding or reduced spring travel.
