Correct fastener selection is critical to ensuring a leak-free flanged joint and long-term operational safety. The bolt grade, nut grade, material, and coating must be matched to the operating pressure, temperature, and media. Our technical team recommends evaluating four key factors before finalizing a fastener for export:
If you are unsure which fastener specification best suits your application, our technical team is available to review your flange drawings, process data, and project specifications — and recommend the most suitable fastening solution for export.
