Fastener selection starts with the complete connection: the threaded or locating element, mating parts, material and required assembly condition. Bolts, screws, studs, nuts, washers and other fixing components perform different functions and are not interchangeable solely because their nominal size appears similar. Foundry Queen enquiries should state the exact drawing or reference, thread details, quantity, material and surface condition. Identify any required marking, packaging and inspection records. Illustrations show general product families and do not define the rating or suitability of a particular connection. Explore the linked product type pages for enquiry planning. Images are product type illustrations; final geometry and supply requirements follow the approved drawing and quotation.
