Groen Z009028 Jacketed Kettle Wing Nut

A threaded fastening component used in commercial kettle systems, this stainless steel wing nut is designed to secure and lock draw-off valve assemblies in place. It features a 10-24 thread configuration that allows it to attach firmly to compatible valve stems, helping maintain a tight and controlled connection. The wing-style design makes it easy to tighten or loosen by hand, which is especially useful during cleaning, maintenance, or routine adjustments in commercial kitchen operations. This part is commonly used with 1-1/2" and 2" draw-off valve stems, where it acts as a knob lock-down nut to keep valve components properly secured during use. In kettles and similar cooking equipment, a loose or missing wing nut can lead to instability in the valve assembly or difficulty in controlling liquid flow. Replacing it helps restore proper fastening and ensures smoother, more controlled operation in food preparation environments such as institutional kitchens, catering setups, and large-scale cooking facilities.
