6、 requirements of the individual product specification shall prevail over those of this specification.1.3 Fasteners are a wide-ranging classification that includes screws, bolts, nuts, washers, stud bolts, rivets, powder-actuatedstuds, staples, tacks, and pins. Bolting, which is composed of bolting m
7、aterials, such as rods, bars, flats, and forgings, which aresubsequently manufactured into bolting components, are a special sub-group of fasteners. Bolting materials and components havedesignated compositions and specific properties intended for applications in aggressive service where commercial g
8、eneric fastenersmay not be suitable or have insufficient fitness for purpose under certain conditions. These conditions include cryogenic or hightemperature service, or excessive vibration, impact, or shock. To further address any other special service conditions where boltingis intended for use, ad

The supplementary requirements only applywhen specified individually by the purchaser in the purchase order or contract.1.
10、5 This specification is expressed in both inch-pound units and in SI units. Unless the purchase order or contract specifies theapplicable “M” specification designation (SI units) the inch-pound units shall apply.
