Professional Applications & Engineering Value

This M39 extra fine thread hex nut delivers critical engineering solutions where vibration resistance and precision alignment are paramount. The 2mm thread pitch creates more thread contact points per unit length, significantly reducing the risk of loosening in machinery, structural assemblies, and heavy equipment subjected to dynamic loads. Manufactured from Class 8 steel, this metric hex nut maintains clamping force integrity in high-torque applications while the Class 6H thread fit ensures consistent engagement with mating components. The DIN 934 standard profile guarantees dimensional accuracy for seamless integration into European-engineered systems across automotive, industrial machinery, and construction sectors where reliable steel fasteners are essential for operational safety and maintenance efficiency.

Specification Summary & Compliance

This precision hex nut features M39 x 2mm extra fine metric threading with Class 6H thread fit tolerance for optimal engagement. The fastener conforms to DIN 934 manufacturing specifications with standard external hex drive (60mm width, 31mm height) and right-hand thread direction. Material certification includes Class 8 strength grade steel construction. Regulatory compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring adherence to current environmental and substance restriction requirements for industrial components.
