DIN933 Hex Bolt is the most commonly used hex bolt in the metric bolt, DIN933 Hex Bolt common grades are 4.8, 6.8, 8.8, 10.9, 12.9. DIN931 Hex Bolt surface is coated with different coatings for different environments.

ASME Black Half Thread Hex Bolt Class 8.8 steel screws are suitable for fastening most machinery and equipment. To maintain corrosion resistance, use ASME Black Half Thread Hex Bolt with black ultra-corrosion-resistant-coated nuts and washers.

ASTM A325M Hot DIP Galvanized Heavy Hex Bolts are commonly used in critical structural applications such as Bridges, buildings and other infrastructure. Ensuring their quality is critical to the safety and structural integrity of these works. The control and traceability of the A325M heavy duty hex bolt or any fastener is a key aspect of the construction and engineering industry. Safety and structural integrity are the correct applications that distinguish ASTM A325M Hot DIP Galvanized Heavy Hex Bolts. Batch control and traceability help maintain the highest safety standards. Batch control ensures that the bolts used in the project come from the same production batch. This helps maintain consistent quality and ensures that all bolts from a particular batch meet the same specifications and standards. In the rare cases where defects or problems are found in a particular batch of bolts, being able to trace back to the source of those bolts can facilitate an effective recall and replacement. This minimizes downtime and project delays.
