Expansion anchor bolts: how to specify material, size and standard

Anchor bolts are specified by material grade, diameter, length and the standard they are manufactured to. For export orders, the material designation (for example the stainless steel type), the thread and size range, and the surface finish should be fixed in the specification, together with the packing unit and carton quantity. Ask for material certificates and dimensional inspection records for the batch, and confirm the standard the buyer's market requires. Samples of the exact size should be approved before a container-load order.
