Professional Applications & Engineering Value
This M20 hex head screw is engineered to address critical fastening challenges in demanding sectors such as machinery assembly, structural frameworks, and heavy equipment manufacturing. The 18-8 stainless steel material delivers excellent corrosion resistance, reducing maintenance costs and extending service life in humid or chemically aggressive settings. Its partially threaded configuration minimizes stress concentration, while the coarse metric thread (M20x2.5) ensures rapid installation and reliable hold in softer substrates or pre-tapped holes. With an external hex drive and compliance to DIN 931, this screw provides consistent torque transmission and interchangeability, making it a trusted choice for engineers seeking durability, efficiency, and compliance in industrial applications.
Specification Summary & Compliance
This product adheres to DIN 931 specifications, with a Class 6g thread fit ensuring precise dimensional accuracy and thread engagement. The screw features a metric coarse thread (M20x2.5) and is partially threaded with a minimum thread length of 52mm and overall length of 130mm. It is manufactured from 18-8 stainless steel and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards, supporting sustainable and safe usage in various industrial sectors.
