• Optimized thin profile design (11mm height) saves space and weight without compromising on strength, perfect for compact assemblies
• Precise Class 6H thread fit ensures reliable mating with bolts, minimizing the risk of cross-threading and assembly errors
• Robust external hex drive allows for high-torque installation using standard tools, speeding up maintenance and installation processes
• Compliance with DIN 439B standard guarantees dimensional accuracy and interchangeability, streamlining procurement and inventory management
• Environmental regulation adherence with RoHS 3 and REACH compliance ensures suitability for global industrial supply chains

Professional Applications & Engineering Value

This M22 left-hand hex nut is engineered to address specific industrial challenges where reverse-thread fastening is critical. Its 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, making it suitable for marine, chemical processing, and outdoor equipment. The thin profile per DIN 439B is particularly valuable in confined spaces, such as machinery guards, conveyor systems, and automotive components, where standard nuts are too bulky. The coarse 2.5 mm pitch and Class 6H thread fit ensure quick assembly and reliable performance under vibration, reducing downtime. With its external hex drive, it facilitates easy installation and removal with common wrenches, enhancing maintenance efficiency in production lines and heavy-duty applications.

Specification Summary & Compliance

This nut features a metric M22 x 2.5 mm coarse thread with left-hand direction and Class 6H thread fit for precise tolerance. It conforms to DIN 439B specifications, ensuring dimensional accuracy with a width of 32 mm and height of 11 mm. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable industrial use.
