I would never use zinc plated hardware outdoors. Stainless steel may work, I
am not sure why you need 3/8-24 instead of 3/8-16.  There are many reports
of the Orion clamp slipping so I assume that you have to bolt it very tight
which may break the stainless steel hardware.  A stronger option that has
good corrosion protection is armor plated bolts. Both SS and armor plated
bolts are available at McMaster-Carr.

I need to replace the rotor-to-mast-clamp bolts on my OR 2800.   They are 
3/8-24 x 4" Grade 5 bolts zinc plated, and are totally rusted.
Since I live on salt water, I would prefer to replace them with  stainless.
My question is: Is there any problem replacing the Grade 5, zinc plated  
bolts with stainless in this application?  Also, what is a good source  for 
3/8-24 x 4" ss bolts.
Tnx, George
