Mike, Jim, List,
Most of the replacement hardware I have used has been AN (some MS);
that's because I have tons of it left over from aircraft rebuilding One
of the advantages of Grade 8 is the plating; grade 5 is usually Type I
cad; while grade 8 is Type II (cad- chromate). Type II is far superior
to Type I when it comes to corrosion resistance.
When I started rebuilding my aircraft in about 1960-1964 in Richmond,
metropolitan population maybe 400,000, there were probably 6 shops
selling aircraft hardware; at least one on every airport.
Now, in Phoenix, population 2.4 million, there is 1 (ONE)! I know every
major hardware manufacturer and vendor in the country; even the people
who supply people like Aircraft Spruce and Specialty and McMaster-Carr,
and all of their prices have skyrocketed; no one carries an inventory,
and shipping cost have gone through the roof.
The price difference between 5 and 8 is not terrible, and, I think,
worth the plating alone.
