EN14399 high-strength structural bolts are manufactured to European standard EN14399 for use in critical load-bearing connections in steel structures. These bolts are available in Class 8.8 and Class 10.9, with hexagon head geometry and heat-treated carbon steel or stainless steel variants. The product is designed for use in bridges, towers, and industrial frameworks where high preload and fatigue resistance are required.
The bolts are produced with controlled heat treatment to achieve specified mechanical properties, including tensile strength and impact resistance. Surface treatments include hot-dip galvanizing (HDG), zinc plating (YZP), Dacromet, and plain finishes. Stainless steel options are available in A2 and A4 grades for corrosion resistance. The manufacturing process follows strict dimensional controls to ensure compatibility with EN14399-6 and EN14399-7 washers and nuts.
These bolts are sourced by engineering contractors, structural fabricators, and infrastructure project suppliers in Europe, North America, and the Middle East. Typical order quantities range from 1,000 to 50,000 pieces per batch. Packaging is in sealed plastic bags inside cardboard boxes or wooden crates, depending on volume. Delivery terms are commonly FOB Ningbo or CIF, with lead times of 3 to 6 weeks after order confirmation.

Verify the bolt class and material grade for each order - Class 8.8 and 10.9 have distinct mechanical properties. Request material test reports for tensile strength, proof load, and hardness for every batch. Confirm surface treatment type and coating thickness with independent test data. Do not accept generic compliance statements without supporting documentation.
Lead time is typically 3 to 6 weeks from order confirmation. Confirm Incoterms - FOB Ningbo is standard, but CIF or DAP may be negotiable. Payment terms are commonly 30% advance and 70% against BL copy. Packaging must be moisture-resistant and labeled with batch numbers and product codes. Always request a packing list with quantity per box and total weight.
Upon receipt, inspect for surface defects, thread damage, or incorrect finishes. Use a thread gauge to verify compliance with 6g tolerance. Perform a random sample of bolts for hardness testing if critical to your application. Retain samples from each batch for future audits. Document any non-conformities immediately and notify the supplier with photos and test results.
