Professional Applications & Engineering Value
This M20 thin hex nut delivers exceptional engineering value through its optimized zinc-plated steel construction and standardized metric coarse thread design. The combination of Class 04 strength grade and thin profile addresses critical space constraints in machinery assembly, automotive components, and structural frameworks where standard nuts would be impractical. The 2.5mm coarse thread pitch facilitates rapid installation in production environments while resisting vibration-induced loosening. Engineered to DIN 439B and ISO 4035 specifications, these industrial hex nuts provide reliable performance in heavy-duty applications where consistent clamping force and corrosion protection are essential for long-term operational integrity.
Specification Summary & Compliance
This metric hex nut features precise M20 x 2.5mm coarse threads with Class 6H thread fit tolerance, ensuring compatibility with standard Class 2A bolts. Manufacturing complies with DIN 439B and ISO 4035 standards for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, confirming environmental safety and regulatory adherence for industrial distribution and use.
