Gibraltar KNL-2-PT-G Knob Handle Plunger 5/16-18

Product Description

The GIBRALTAR KNL-2-PT-G is a non-locking knob handle plunger designed for indexing, positioning, and light clamping applications in industrial and mechanical assemblies. It features a 5/16-18 threaded shank with a 0.625-inch thread length and a knurled knob head for manual actuation without tools. The spring-loaded steel plunger delivers an initial end force of 1 pound and a final end force of 6 pounds, making it suitable for applications requiring repeatable, low-force positioning. The body measures 0.76 inches in length with a maximum plunger diameter of 0.154 inches. A zinc gold chromate finish provides corrosion resistance. Installed by machinists, maintenance technicians, and assembly professionals.

This plunger is used in fixtures, jigs, machine tool components, and industrial equipment where a manually retractable locating pin is needed. The knurled knob allows hand operation in confined spaces without a wrench. With a plunger projection of 0.188 inches and a plunger length of 1 inch, it fits standard threaded bosses in light-duty positioning and detent applications. The locking element engages the threaded bore to secure the assembly in place once installed.

Installation Notes

Installation is performed by threading the plunger body into a tapped 5/16-18 bore by hand or with a wrench on the knob flats until the shoulder seats. De-energize or lock out any machinery before installing or replacing plungers in live equipment. Verify bore thread condition and depth before installation to prevent cross-threading. Do not exceed the rated end force range by substituting springs or modifying the plunger body.
