Professional Applications & Engineering Value
This M18 thin hex nut, manufactured from zinc-plated steel, is engineered to address common challenges in industrial fastening, such as corrosion and space constraints. Its thin profile is particularly valuable in compact assemblies found in machinery, automotive sub-assemblies, and electrical enclosures, where every millimeter counts. The coarse thread pitch and Class 6H thread fit ensure rapid assembly and a secure, vibration-resistant connection, reducing maintenance needs. Conforming to DIN 439B and ISO 4035 standards, it guarantees dimensional precision and interchangeability, making it a reliable component for B2B procurement in manufacturing, construction, and MRO operations.
Specification Summary & Compliance
This nut features an M18 x 2.5 mm coarse thread with a Class 6H thread fit per ISO standards, ensuring high dimensional accuracy. The external hex drive has a width of 27 mm and a thin height of 9 mm, conforming to DIN 439B and ISO 4035 specifications. It carries a Class 04 strength grade and is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives.
