They worked perfectly

In stock, arrived promptly and well packaged. No issues noted during installation..

SUPERIOR SA531001 NUT, CYLINDER HOLD DOWN
It worked fine. Can be stretched over the (protected ) propeller hub without heating if OAT is warm (it was about 90F).. takes some technique (that our mechanic had) but no special tools, other than a screwdriver for leverage, on a continental motor. There are several bulletins dealing with installation but it basically needed a non hardening adhesive for the OD and just engine oil for the ID. Bulletin says to run the engine to check for leaks but you should not do anything for 24 hours to let the sealant set (I found out the hard way!).
