Thread: Which Bolts to use

yeah good point Dougal.
Im unsure of the process but the structural grade bolts I source have a very thick Zn coating (test with grinder) yet have near perfect tolerances in shank diameter and thread pitch / size. I would use them exclusively but can really only sorce them in the usual "structural" sizes, longer shanked M10, M12, M16, M20 then upwards.

When I galvanised and rebuilt my 110 and (2 x2A's) , I used most of the original bolts but put nickel based anti sieze (looks like silver grease) religiously on just about every thread that didnt require loctite. Even if the original bolts are a little rusty, a wire brushing and the anti-sieze is all they need.
