Stainless rivnuts for bolt-in bow hatch?

Postby Mule » Wed Jun 12, 2019 7:47 am

I'm building a bolt-in bow hatch to cover the recess on my boat. Thinking I could use stainless rivnuts to secure it to the bow on the inside edge of the recess.
My question is: will they hold up long term? I'm going to be putting a pedestal seat base in the hatch frame, so it will need to be able to carry some weight.

Yes. Use 1/4-20 units and do multiple units. Use silver base anti sleeze on bolt threads.. good luck.$

Stainless rivnuts is the perfect recipe for failure. At work we considered stainless hardware single use because when torqued to spec it galled almost every time upon attempted removal. A rivnut will break lose and spin before the screw breaks leaving you in a not fun situation; can’t drill it, can’t break it off...

Cad plated nutplate is what I use.
I'm brand new to jet boats so don't listen to anything I say.
