S-93510A165 M30 DIN 934L Hex Nuts

Key Features & Benefits at a Glance

• Exceptional corrosion resistance from 18-8 stainless steel construction, ideal for harsh environments and extending service life
• Secure left-hand thread engagement prevents loosening in applications with counter-clockwise rotational forces
• Robust coarse pitch thread (3.5 mm) enables faster assembly and disassembly while maintaining high load-bearing capacity
• Precision Class 6H thread fit ensures consistent, reliable mating with bolts for vibration-resistant connections
• Standard external hex drive and profile provides compatibility with common wrenches for straightforward installation
• Compliance with DIN 934L specifications guarantees dimensional accuracy and interchangeability in metric systems
• Environmental regulation adherence with RoHS 3 and REACH compliance for safe use in regulated industries

Professional Applications & Engineering Value

This M30 left-hand thread hex nut is engineered to address critical challenges in industrial settings where standard right-hand threads would unscrew under specific rotational stresses. Manufactured from 18-8 stainless steel, it delivers superior corrosion resistance against moisture, chemicals, and outdoor exposure, making it indispensable for marine equipment, chemical processing machinery, and infrastructure projects. The coarse thread pitch and Class 6H thread fit provide excellent vibration resistance and ease of maintenance in high-stress assemblies, such as rotating shafts, conveyor systems, and heavy-duty fastening applications. Its compliance with DIN 934L ensures precise dimensional stability, while the external hex drive allows for efficient torque application with standard tools, reducing installation time and labor costs in B2B procurement scenarios.

Specification Summary & Compliance

This hex nut features a Metric M30 thread size with a 3.5 mm coarse pitch and left-hand thread direction, manufactured to DIN 934L standards for dimensional accuracy. The thread fit is Class 6H, ensuring tight tolerances for reliable performance. Key dimensions include a 46 mm width and 24 mm height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications.
