is there a better place than mercury to buy 7/16 x 20 nylock mount nuts to bolt up bravo drives. Merc. gets a really health (expensive) price for them i believe. If changing out one or 2 ok, but I want change all on both drives.

Any GOOD hardware store should have them.

Many hardware stores have them. I buy them from McMaster Carr. Box of 20 stainless

My local ACE has an incredible bolt selection. If not, there is a local bolt and fasteners shop by me that also sells everything you can think of. You might have to look around a little

I can tell you not to use the Hillman brand, found at most hardware stores around my area. Maybe yours too ?

2 out of 2 stripped before final torque. Crazy.

Just bought mine at Shop-O-Rama $1.09 each
