Quote: Why wuold you want to buy nuts and bolts from a chandler for fxxxx sake?any hardware store will sort you out for a fraction of the price.
Very few hardware stores stock hot-dipped galvanised fixings. As one of the above posters has pointed out, they are nearly always BZP - bright zinc electro plated. About as much use on a boat as a cardboard wheelbarrow. Even most shackles sold nowadays in the chandlers are electro-plated and go rusty in a matter of weeks.
