Gibraltar KN8C----S5---21 Tapered Shift Knob Female Insert

Product Description

The GIBRALTAR KN8C----S5---21 is a tapered shift knob with a female insert mount, designed for use on threaded control rods and shift linkages in industrial, automotive, and equipment applications. The knob features a 1.6-inch head diameter, a 2.48-inch overall length, and a 0.7-inch hole depth with a 1/2-13 threaded female insert. The base diameter measures 1.0 inch. The black finish and tapered profile are standard for hand-operated shift and control applications. Installation requires no adhesive or secondary fasteners — the female insert threads directly onto a matching male-threaded rod or shaft.

This tapered knob is suited for use on gear shift levers, control rods, and machine handles where a 1/2-13 threaded interface is present. Typical install scenarios include OEM equipment replacement, industrial machinery controls, and aftermarket shift linkage upgrades. The compact form factor fits both light-duty and medium-duty hand-operated mechanisms. Technicians and maintenance professionals working on equipment with standard 1/2-13 threaded shafts will find this a direct-fit solution requiring no modification.

Installation Notes

This knob is installed by a maintenance technician or equipment service professional. Ensure the equipment is powered down and all moving parts are at rest before servicing shift linkage or control rods. Thread the female insert onto the shaft by hand until snug, then tighten to a firm, non-slip engagement without over-torquing the insert. Confirm the knob is fully seated and does not wobble or back off under normal operating force before returning the equipment to service.
