ANSI B18.2.2 Square Nut are Made with top-quality materials, these nuts are known for their durability, strength, and corrosion resistance. ANSI B18.2.2 Square Nut are designed to last. The high-quality steel construction provides excellent tensile strength, meaning they can handle high load capacities without deforming or breaking. Galvanized Carbon steel is also resistant to corrosion, so ANSI B18.2.2 Square Nut stand up well even in wet and humid environments.

As1252 Heavy hexgonal Bolt 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 As1252 Heavy hexgonal Bolt. 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.

DIN7991 Flat Head Socket Bolt is a hexagonal head that allows for easy tightening and loosening, and is made from high-quality steel for maximum durability. With its sturdy construction and robust design, DIN7991 Flat Head Socket Bolt can withstand high levels of stress and strain, making it an ideal choice for heavy-duty applications. Made from high-quality steel, DIN7991 Flat Head Socket Bolt is resistant to corrosion and rust, ensuring reliable performance even in harsh environments. DIN7991 Flat Head 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.

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. 

​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.
