A heavy-duty two-piece flanged cap nut with M22 x 1.5 thread, 33mm hex size, 31mm height, and 48mm flange diameter, generally used with Budd, Gunite, or Webb studs. The integrated flange distributes clamping load evenly and helps prevent loosening under vibration, while the closed cap end protects the wheel stud threads from dirt and moisture. It's used in wheel-end assemblies on heavy-duty trucks and trailers to secure the wheel to the hub.
