Here's my old bolt after it was cut out.

I have been seeking stainless flanged bushings without any luck. Brion referred to a collared bushing". I am assuming he means stainless instead of for example oilite bronze or aluminum. I suppose I could make some on my lathe, but that is a good bit of work and a waste of a lot of material.

Anyone know a source for such stainless collared bushings?

Thanks!

Thanks Brion. Any thoughts about using bronze flange bushings instead of SS?

Hi again,
If it's good bronze, and actual bronze (not brasses like manganese bronze or naval bronze), and if the scantlings are right, bronze is great.

The readily available bronze bushings are scinterd bronze:

86.3-90.5% copper
9.5-10.5% tin
1.0% iron
0% lead
1.7% carbon

No zinc which I think is a good thing for strength. But that one percent iron would seem to be problematic in the marine environment.

Also, SAE 660 bronze:

83% copper
7% tin
7% lead
3% zinc

for which it is said: The alloy is not subject to dezincification and has reasonable corrosion resistance to seawater and brine making it suitable for pump and valve components.

Thoughts?
