Nuts and bolts for perkins 4108 external parts ( and paint!)

[pcatterall]

As I strip the 4108 which I hope to restore I am trying to restore all the bolt ons as I go.
many of the nuts and studs are very rusty so I want to replace as I go along.
I would ideally like to buy in a stock of commonly used nuts, bolts, studs and washers so I have them to hand.
Are there recommended stockists who offer a 'kit' or selection which I could buy?
Is there a 'superior' steel spec for marine use?

I mention paint as I am told that the best way to refurbish an engine is to paint it!! more seriously I do hope to give the parts some good
protection and stave off the ravages of marine conditions. I am treating rust as I go and it would be nice to learn of any tricks and recommended paints.
It would be good to get spray paint for smaller bits as I go along so as not to be throwing brushes away all the time ( or cleaning).

Thanks for any tips.

When I was restoring my MGB I went to a local nut & bolt supplier and purchased a range from 1/4 " to 3/8" UNF in various lengths 1" to 1 1/2" and had then zinc plated to prevent rusting.

I did the same on my perkins 4 236 and replacing as I go along.

You first need to identify the threads that you need. If metric, then no problem. Unified and BS are scarcer. You should have good engineer's stockists in Lancahire. My local one is very obliging, with a range of good quality stock.
Alternatively, ebay has plenty of reputable suppliers and a very wide range of specs. including less common ones. Small quantities are no problem either.
Stainless steel might be worth considering for some applications, again readily obtainable, otherwise normal 8.8 tensile grade is probably good for general use on an engine, nuts are less often graded.
Studs might be harder to source. Don't cut from lengths of threaded rod if you can help it.
Look for marking on the hexagons.
Bright zinc plated fasteners from DIY outlets can be at the lower end of the quality range.

Buy a can of polycleans brush cleaner (assuming that grade of thinners) & clean the brush & wrap it in cling film, Pull the hairs in tight so that the brush has a nice tight form when ready to be re used. Store it in the cling film in its wet state. Even if there is a bit of paint still in the brush it should be OK for quite a while

For aerosol paint, smooth Hammerite works well.
