Professional Applications & Engineering Value

Engineered for demanding industrial applications, these black-oxide 18-8 stainless steel hex nuts combine material excellence with precision manufacturing. The M4 coarse thread with Class 6H tolerance ensures secure fastening in vibration-prone equipment, while the external hex drive accommodates high-torque installation in confined spaces. The black-oxide surface treatment enhances corrosion protection in automotive assemblies, electrical enclosures, and marine hardware, preventing galvanic corrosion when paired with compatible fasteners. Compliance with DIN 934 standards makes these nuts suitable for European machinery exports and maintenance operations requiring metric thread consistency.

Specification Summary & Compliance

This standard hex nut features M4 x 0.7 mm coarse metric threads with Class 6H thread fit per ISO standards, ensuring precise engagement with mating components. Manufacturing follows DIN 934 specifications for dimensional consistency (7mm width, 3.2mm height). The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances above threshold limits.
