Engine Shaft Nuts and Spinner Nuts
The engine shaft nut secures the prop or spinner to the crankshaft, and using the right thread and material keeps that connection tight under running vibration. This category collects shaft nuts in common threads and both steel and aluminum.
Thread Sizes
Options include 3/8-24, 1/4-28, and 8x1.25mm engine shaft nuts, so you can match the nut to the threads on your engine's crankshaft. Threading the wrong pitch onto a shaft can damage it, which makes matching the size the first step.
Steel and Aluminum Nuts
Hardened steel hex nuts in black offer strength for a standard mount, while aluminum hex and aluminum spinner nuts, including the Du-Bro 8 by 1mm spinner nut, save weight or seat inside a spinner backplate. Choosing steel or aluminum depends on your setup and whether a spinner covers the nut.
