One of my windows looks a bit cool. Its got some counter sunk bolts that are brass coloured. I've taken the large side window out to try and sort the leak out, and want to put it back in using 'the cool counter sunk bolts' that my other window has. Any idea what they will be made from?
They were probably chromed brass originally but the chrome has worn off.
Assuming your windows are anodised aluminium (a matt silver finish) then you might do better buying aluminium nuts and bolts if you can get them - a window manufacturer might have some. Failing that stainless steel, again ebay is your best friend for prices, although there is a risk of crevice corrosion behind them in sea water but I guess that won't be an issue with you.
Make sure you buy "set-crews" and nyloc nuts, set-screws are threaded all the way up whereas bolts or machine screws are not always threaded enough for purpose. Nyloc nuts won't work loose.
Certainly nuts and bolts and not plain screws or "pop" rivets will allow you to pull the windows up over the butyl bedding mastic strip (buy from caravan suppliers on e-bay, not the local swindlery) to get a good seal.
I used mastic strip once and it was a PITA, I went for neoprene tape after thet and it was so much easier and sealed well once pulled up, as clive says stainless csk screws but I wouldn't worry about nylocs, acorn nuts look nice inside (dome nuts but slightly taller).
brass or copper bolts round windows?
