Materials and Manufacture4.1 Materials:4.1.1 The bolts, cap
20、screws, and studs shall be manufacturedfrom material having a chemical composition conforming tothe requirements in Table 1 and capable of developing therequired mechanical properties for the specified alloy in thefinished fastener. See Specification B 574 for nickel alloys.4.1.2 The starting condit
21、ion of the raw material shall be atthe discretion of the fastener manufacturer but shall be suchthat the finished products conform to all of the specifiedrequirements.4.2 Manufacture:4.2.1 FormingUnless otherwise specified, the fastenersshall be cold formed, hot formed, or machined from suitablemate
