Composition, pitting-resistance data and property classes from A240, the Outokumpu handbook and ISO 3506.Copper, Brass and Bronze Fasteners: Where Each Material FitsPure copper excels at conductivity, brass at machining, phosphor bronze at spring performance and silicon bronze in exposed service. Here is where each material fits.What Do Washers Do? Types, Functions, and SelectionChoose washers by the problem they solve: bearing pressure, elastic movement, or rotational loosening. Compare standard dimensions, hardness, and spring-load data.How to Specify a Bolt: Size, Thread, Grade, and FinishRead inch and GB/T metric bolt callouts, then complete the size, grade, material, finish, mating hardware and inspection requirements on your RFQ.
