Prop Shaft Castle Nut 7/8" for 1-1/4" Shaft

Part #: T1955
This 7/8"x9 brass castle nut is used only on 1-1/4" diameter shafts (remember the shaft is tapered at the prop). A square key and a cotter pin are also included.
Just a note of interest... Although mild steel and hardened steel castle nuts are readily available, brass castle nuts are not. They must be individually machined for us from a heavy profile, commercial brass nut, hence the surprising cost for a single nut.
Thread size: 7/8" x 9
