Professional Applications & Engineering Value
This M3 brass hex nut is engineered to address common challenges in electrical, plumbing, and marine applications where corrosion and conductivity are critical. The copper alloy construction naturally resists rust and galvanic corrosion, extending service life in harsh conditions. Its Class 6H thread fit and DIN 934 standard profile ensure precise mating with metric coarse threaded bolts, minimizing the risk of cross-threading and loosening under vibration. The standard external hex drive facilitates quick installation and removal with standard tools, boosting efficiency in assembly lines and maintenance tasks. Ideal for electrical enclosures, control panels, and non-sparking environments, this nut combines material benefits with stringent manufacturing standards for reliable performance.
Specification Summary & Compliance
This M3 x 0.5 mm coarse thread hex nut features a Class 6H thread fit per ISO metric standards, with a width of 5.5 mm and height of 2.4 mm. Manufactured to DIN 934 specifications for dimensional consistency and right-hand threading. It is RoHS 3 compliant (with exemption 6c for lead in copper alloy) and REACH compliant (as of 01/17/2022, 223 SVHC), ensuring adherence to environmental and safety regulations for industrial use.
