Before ordering, confirm the exact material grade and surface finish per international standard (e.g., ASTM, ISO). Request material certificates (EN 10204 3.1 or 3.2) for each batch. Verify thread dimensions with a calibrated gauge and ensure the bolt length includes the full threaded section on both ends. Do not accept generic claims without test data.
Lead time is stated as 30 days or quantity-dependent - confirm exact delivery schedule for your order volume. Incoterms are not specified; request FOB Shanghai, CIF destination, or other terms with clear responsibility boundaries. Payment terms include TT, LC, and Western Union - avoid full prepayment without a purchase order and shipping documentation. Ensure the supplier provides a bill of lading and packing list.
Conduct a pre-shipment inspection for thread quality, surface finish uniformity, and absence of burrs or cracks. Request a sample batch for destructive testing if critical. Verify packaging is moisture-resistant and labeled with part number, quantity, material, and batch ID. Retain samples for quality traceability. Ensure the supplier provides a certificate of conformity and test reports for each shipment.
