HIGH STRENGTH BOLTED CONNECTIONS IN STEEL CONNECTIONS--PROTECTION OF BOLTS, NUTS AND WASHERS

The codes of practice for the calculation, design and construction of slip-proof bolted connections (high strength bolted connections) issued either in the various countries or by both the European federations of steel construction companies and the International Union of Railways have not so far given any instructions for the direct protection against corrosion of either faying surfaces or of bolts, nuts and washers. It may be anticipated that it is possible to reduce the effect of corrosion on bolt shanks and inner faces of drilled holes by protecting the faying surfaces with metal coatings of aluminum or zinc or with alkaline silicate zinc dust paint. The diffusion of moisture between the faying surfaces to the drilled holes may be lower than that with unprotected faying surfaces. This arises when the external protection of the assembled connection is defective or missing.
