Hi I dropping my shafts to do cutluss bearings and looking for spare and replacement Nylok nut for 1 3/4” shaft attached to coupler. I believable it looks like it is brass material but I cannot find the exact Nylok Nut. I have searched the web and cant find anything can anybody HELP PLEASE! Thank you!!

Did you check Grainger and McMaster Carr?

Welcome to the forum.......Just to add to the above......Try marine shops that repair propellers and shafts, sell couplings and coupling parts etc.

Is there a valid reason for swapping out for new ones? A Nyloc nut can be used several times. The nylon portion only acts as a friction lock and has no bearing on the actual strength of the nut. Removal several times will eventually lead to wearing out the nylon however in your application it has maybe been removed once or twice.

Thanks Bud37, I will be checking that out as well I stumbled upon a Marine shafts, Props and coupler place on the web who seems like they may carry it but they were closed over the weekend. The place is called MarineHardware.com Im not sure how reputable they are.

Thanks Midnightsun, I know they were taken off once or twice before and I did not want to chance the strength or integrity of the nylon from being worn especially with these couplers Not having a setscrew I wanted to be certain that Nylok was fresh. I started to remove the lock nut and 1 point out of the 6 on the nut got filed down a touch from using a spindle remover in the pic below. I did a bit more research and was told I have to improvise with a 1-13/16” socket and shave down the outer walls so it can seat in the coupler to remove.
