DIN912 Hex Socket Bolt With its high strength, ease of use, versatility, and corrosion resistance, it is no wonder that it is a popular choice for a wide range of applications.

​DIN21346 Square Bolt are similar to Hex Cap screws but have a 4-sided square head instead of a 6-sided hexagonal head.They are commonly referred to as both bolts and screws and are designed to be driven with a wrench. DIN21346 Square Bolt are partially threaded with a shoulder beneath the head.

ASTM A325M HEAVY HEX STRUCTURAL BOLTS METRIC 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 HEAVY HEX STRUCTURAL BOLTS METRIC. 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.

Welding Stud Connector Aws D1.1 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 Welding Stud Connector Aws D1.1 for through deck and straight to steel welding. Welding Stud Connector Aws D1.1 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.
