Professional Applications & Engineering Value
This M20 hex head screw is engineered to address critical challenges in heavy-duty applications, such as construction, machinery assembly, and structural frameworks. The hot-dipped galvanized steel material provides a robust barrier against moisture and chemicals, preventing rust and maintaining integrity in corrosive environments. With a partially threaded design and coarse thread (M20x2.5), it offers efficient grip and vibration resistance, reducing the risk of loosening in dynamic loads. The Class 10.9 strength grade and precise Class 6g thread fit ensure reliable clamping force, making it ideal for high-tensile scenarios where failure is not an option. By complying with DIN 6914/ISO 7412 standards, these screws deliver consistent performance, minimizing downtime and enhancing safety in industrial settings.
Specification Summary & Compliance
This fastener features a metric coarse thread with M20 size, 2.5 mm pitch, and Class 6g thread fit for precise dimensional accuracy. It adheres to DIN 6914/ISO 7412 manufacturing specifications, ensuring uniformity and reliability. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms it is free from hazardous substances, supporting sustainable and safe industrial use.
