Professional Applications & Engineering Value

This zinc-plated steel flange nut delivers critical engineering solutions where vibration resistance and corrosion protection are paramount. The integrated 34.5mm flange eliminates separate washers while distributing clamping force across wider surfaces - preventing material deformation in structural steel assemblies, heavy machinery, and transportation equipment. The M16x2mm coarse thread with Class 6H precision maintains reliable engagement under dynamic loads, while the external hex drive facilitates rapid installation in confined spaces. Manufactured to DIN 6923 and ISO 4161 standards, this Class 10 heavy-duty flange nut provides certified performance for automotive, construction, and industrial maintenance applications requiring long-term fastener reliability.

Specification Summary & Compliance

This metric flange nut features M16x2mm coarse threads with Class 6H fit tolerance, 34.5mm flange diameter, and 2.4mm flange thickness. Manufactured according to DIN 6923 and ISO 4161 specifications with Class 10 strength rating. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
