Start with the product family
Bolts, screws, nuts and washers are used in threaded assemblies. Rivets, pins and retaining rings have different connection and retention functions. Anchor rods and post-installed concrete anchors are separate families.
Define geometry before performance
Diameter and length alone are not a complete part reference. Identify thread system and pitch, head or body form, relevant tolerances and the required standard or drawing.
Complete the purchase brief
Include quantity, material designation, grade, finish, accessories, delivery country and inspection documents. A clear RFQ reduces assumptions at quotation stage.
