S-93031A132 M6 DIN 439B, ISO 4035 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction, ideal for chemical, marine, and outdoor applications
• Secure reverse-thread locking with a left-hand thread direction, preventing loosening in applications where standard right-hand rotation occurs
• Precise, reliable fine threading with a 0.75mm pitch and Class 6H fit, ensuring tight, vibration-resistant connections in critical assemblies
• Space-saving, lightweight design with a thin profile (3.2mm height), perfect for applications with limited clearance without sacrificing strength
• Guaranteed dimensional accuracy and interchangeability, manufactured to meet DIN 439B and ISO 4035 international standards
• Easy installation and removal with a standard external hex drive (10mm width), compatible with common wrenches for efficient maintenance
• Compliance with stringent environmental regulations, being RoHS 3 and REACH compliant for safe use in regulated industries

Professional Applications & Engineering Value

This M6 left-hand thread hex nut is engineered to solve specific industrial challenges where standard fasteners fail. Its 316 stainless steel material provides exceptional resistance to corrosion from chemicals, saltwater, and extreme temperatures, making it indispensable in marine equipment, chemical processing plants, and food machinery. The left-hand thread is critical for assemblies with rotating components that naturally turn counter-clockwise, preventing unintended loosening and enhancing operational safety. The thin hex nut profile and metric fine thread (0.75mm pitch) allow for a compact, high-strength fit in tight spaces, reducing assembly weight and bulk while maintaining a secure, vibration-resistant hold under dynamic loads. Manufactured to DIN 439B and ISO 4035 standards, it ensures reliable performance and compatibility in global engineering projects.

Specification Summary & Compliance

This nut features an M6 thread size with a 0.75mm fine pitch and Class 6H thread fit for precise dimensional tolerance. It conforms to DIN 439B and ISO 4035 specifications for thin hex nuts, ensuring consistent quality and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances and safe for industrial use.
