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.

DIN961 Hex Bolt is the most commonly used hex bolt in the metric bolt, DIN961 Hex Bolt common grades are 4.8, 6.8, 8.8, 10.9, 12.9. DIN961 Hex Bolt surface is coated with different coatings for different environments.

ISO4014 Hex Bolt is the most commonly used hex bolt in the metric bolt, ISO4014 Hex Bolt common grades are 4.8, 6.8, 8.8, 10.9, 12.9. ISO4014 Hex Bolt surface is coated with different coatings for different environments.

DIN127b Metal Spring Washer are commonly used metric lock washers, DIN127b Metal Spring Washer a split metal ring that is bent into a helical shape. DIN127b Metal Spring Washer are a left hand helix and allow the nut to be tightened in a right hand direction only. When compressed by tightening the nut, the washer bites into the substrate and exerts a spring force between the bolt and the substrate creating frictional resistance to rotation.
