ABSTRACT
These documents are of interest because, although focused on structural steel applications, they are the only bolting specifications, of which we are aware, that not only provide authoritative criteria for strength of joints subject to various loading conditions but also tell the designer and user how much tension or preload is required (when preload is required) in installed bolts. To do this, the specifications address all significant factors affecting the bolts, from their selection by the designer to their inspection upon receipt at the job site, handling and storage, verification of the suitability of fastener components (bolts, nuts, washers and
lubrication thereof; each probably from more than one source) plus their suitability as an assembly and when installed by the method to be used in the work to achieve the specified pretension. They then specify how to achieve the required preload and how to inspect for it.
