Very good...but why cut the hex portion back so far? It would be better to have nut flush with crankshaft end. Better holding & more of the hex is there in case you want to remove to do repairs later if needed. Capt,n
You have to cut a small part of the hex off to clear the centering stub on the SBA. Look at the other picture I posted, it's easy to see there is plenty of hex left to work with. Anyone that routinely strips the hex off of spark plugs should maybe have it done for them.
