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.

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. 

Shear Stud Welding Nelson Stud are used in stud welding to secure steel framed buildings to create a shear connection between the steel and the concrete. We supply and fix all available sizes of Shear Stud Welding Nelson Stud for through deck and straight to steel welding. Shear Stud Welding Nelson Stud are designed to tie the concrete to the steel beams and to resist shear loadings between the concrete slab and steel beam in composite construction.
