Gibraltar DKN25-G Knob Handle Spring Plunger 1/4-20

Product Description

The GIBRALTAR DKN25-G is a non-locking knob handle spring plunger designed for indexing, positioning, and light-duty retention applications in mechanical assemblies. The plunger features a Delrin knob for manual actuation without tools and a spring-loaded nose that provides controlled end force ranging from 0.12 pounds initial to 0.36 pounds final. With a 1/4-20 thread and 0.5 inches of thread length, this plunger installs into standard tapped holes in machine frames, fixtures, tooling plates, and enclosures. Machinists, maintenance technicians, and equipment builders commonly install this type of component during fixture setup or equipment assembly.

The DKN25-G suits light-duty positioning tasks in industrial equipment, jigs, fixtures, and panel assemblies where repeatable manual indexing is needed. The non-locking plunger design allows the nose to retract and extend freely under manual pressure, making it appropriate for applications that require frequent adjustment or quick-release indexing without additional fasteners or tools.

Key Features

• Non-locking plunger design for tool-free manual actuation
• Delrin knob provides comfortable grip and corrosion-resistant contact surface
• 1/4-20 thread for installation into standard tapped holes
• Initial end force of 0.12 pounds, final end force of 0.36 pounds for predictable spring resistance
• Compact body length of 0.63 inches suited for space-constrained assemblies
• Maximum plunger diameter of 0.16 inches with 0.13 inches of plunger projection

Compatibility

Designed for use in standard 1/4-20 tapped holes in mechanical fixtures, tooling plates, enclosures, and light industrial equipment where a non-locking spring plunger with a knob handle is required.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped 1/4-20 hole by hand or with a wrench on the hex flat. Ensure the mating hole depth and thread engagement are sufficient to support the specified end forces without bottoming the plunger body. De-energize or secure any moving assembly before servicing adjacent components. Do not exceed the rated end force range to avoid spring fatigue or premature wear.
