Gibraltar DKN38-PT-G Knob Handle Plunger 3/8-16

Product Description

The GIBRALTAR DKN38-PT-G is a non-locking knob handle plunger designed for use in indexing, positioning, and clamping applications across industrial and mechanical assemblies. It features a 3/8-16 threaded shank with a 0.75-inch thread length and a Delrin knob for hand-tightening without tools. The steel body with a black finish measures 0.94 inches in body length. The plunger has a maximum diameter of 0.25 inches and a total plunger length of 1.4 inches. End force ranges from 0.25 pounds initial to 2 pounds final, making it suitable for light-duty locking and positioning tasks in fixtures, jigs, and tooling setups.

This plunger is used in industrial fixtures, machine tooling, and mechanical assemblies where repeatable hand-operated positioning is required. The knob-style design allows operators to engage and disengage the plunger quickly without tools. The 0.19-inch plunger projection and 0.75-inch length under the head provide consistent engagement depth for standard tooling panels and fixture plates. It is a common choice for maintenance technicians, machine builders, and toolmakers working with light-duty positioning hardware.

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial fixtures, jigs, and tooling assemblies requiring a 3/8-16 threaded non-locking knob plunger.

Installation Notes

Installation is performed by threading the 3/8-16 shank into a tapped hole in the fixture plate or panel to the required engagement depth. Ensure the mating thread is clean and free of debris before installation. No special tools are required for the knob handle, though a wrench may be used on the hex feature during initial installation to achieve proper seating. Confirm plunger projection and end force are appropriate for the application before placing the assembly into service.
