The AYP 182398 is a genuine OEM handlebar wing nut designed for securing the upper and lower handle assemblies on various lawn mowers, garden tractors, and snow throwers. This durable wing nut ensures a firm and stable connection, preventing handle movement during operation. It is a direct replacement for the original part, commonly found on AYP, Craftsman, Husqvarna, and Poulan equipment, and features a 5/16-18 thread for easy installation and removal without tools.
