Before ordering, verify the exact grade (A325 Type 1 or A490 Type 1) and finish to ensure compatibility with your project’s environmental and load-bearing requirements. Confirm whether full or half thread lengths are needed, as this affects installation and structural integrity. Request samples for testing if the application involves critical stress points or corrosive conditions.
Confirm logistics details such as lead time, which can vary based on order volume and customization requirements. Clarify Incoterms (e.g., FOB Ningbo) to determine responsibility for shipping costs and risk transfer points. Payment terms should also be discussed, with options typically including T/T or L/C for international transactions.
Inspect the bolts upon arrival for dimensions, thread quality, and finish consistency. Request a material test report (MTR) to confirm compliance with ASTM standards for tensile and yield strength. Ensure all documentation, including certificates of origin and compliance, is provided to facilitate smooth customs clearance and project approvals.
