Professional Applications & Engineering Value

This M4 thin brass hex nut delivers exceptional engineering value through its optimized material selection and precision manufacturing. The brass construction provides natural corrosion resistance that outperforms steel alternatives in moisture-prone applications, eliminating the need for additional coatings while maintaining electrical conductivity. The thin profile design (2.2 mm height) solves space constraint challenges in compact assemblies, electronic enclosures, and instrumentation panels where standard nuts would be impractical. With metric coarse threading (0.7 mm pitch), installation efficiency is maximized while reducing the risk of cross-threading during high-volume assembly operations. The combination of DIN 439B and ISO 4035 compliance ensures global interoperability, making these nuts suitable for export equipment, automotive subsystems, and precision mechanical assemblies requiring reliable, vibration-resistant fastening solutions.

Specification Summary & Compliance

This precision fastener features M4 x 0.7 mm coarse metric threading with Class 6H thread fit tolerance according to ISO standards, ensuring consistent engagement and reliable performance. The nut conforms to DIN 439B and ISO 4035 dimensional specifications with 7 mm width across flats and 2.2 mm height. Manufacturing compliance includes RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and full REACH (EC 1907/2006) compliance regarding SVHC substances as of January 2022. The right-hand thread direction and external hex drive design provide standard compatibility with metric tooling systems worldwide.
