Professional Applications & Engineering Value
This M42 thin hex nut delivers critical engineering advantages where space constraints and corrosion resistance are paramount. The zinc-plated steel construction provides essential protection against oxidation in manufacturing facilities, outdoor equipment, and marine applications. With its 4.5 mm coarse thread pitch, this fastener enables rapid assembly in high-volume production environments while maintaining secure connections under vibration. The thin hex profile allows installation in tight clearance applications where standard nuts cannot fit, making it ideal for machinery, structural frameworks, and transportation equipment. Compliance with DIN 439B and ISO 4035 standards ensures consistent quality and interchangeability across global supply chains, while the Class 6H thread fit guarantees precise mating with corresponding bolts for leak-proof and reliable joints.
Specification Summary & Compliance
This metric hex nut features M42 x 4.5 mm coarse threads with Class 6H thread fit tolerance per ISO standards. Manufacturing conforms to DIN 439B and ISO 4035 dimensional specifications, ensuring 65mm width across flats and 21mm height. The fastener meets Class 04 mechanical properties and carries full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for regulated industrial applications worldwide.
