Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and prolonged outdoor use.
- High tensile strength of 100,000 psi ensures reliable performance under heavy loads and mechanical stress.
- Coarse thread design (M20 x 2.5mm pitch) allows for faster assembly and reduced risk of cross-threading in demanding applications.
- Precise Class 6g thread fit guarantees consistent engagement and secure fastening, minimizing loosening over time.
- External hex drive and hex head provide easy installation and removal with standard tools, enhancing workflow efficiency.
- Partial threading offers optimal grip and clamping force where full threading isn't required, reducing material usage without compromising strength.
- Compliance with RoHS 3 and REACH ensures environmental safety and regulatory adherence for global industrial supply chains.
Professional Applications & Engineering Value
This M20 hex head screw is engineered to address common industrial challenges, such as vibration-induced loosening and environmental degradation. Crafted from 18-8 stainless steel, it resists rust and corrosion in humid or chemical-exposed settings, extending service life in machinery, structural frameworks, and marine equipment. The coarse metric thread and Class 6g thread fit ensure quick, reliable installation in high-volume production lines, while the external hex drive allows for high-torque application without stripping. Ideal for construction, automotive, and heavy equipment assemblies, this screw delivers consistent performance where durability and regulatory compliance are critical.
Specification Summary & Compliance
This screw adheres to ISO 4014 DIN 931 standards, with a Class 6g thread fit ensuring precise dimensional accuracy for metric coarse threads (M20 x 2.5mm). It is partially threaded with a minimum thread length of 46mm and overall length of 140mm, manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting safe and sustainable industrial practices.
