S-93031A114 M6 DIN 439B, ISO 4035 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments including marine and chemical applications
• Reliable left-hand threading prevents unintentional loosening in rotating machinery and specialized equipment where reverse rotation occurs
• Space-saving thin profile (3.2mm height) provides secure fastening in confined spaces without compromising strength
• Precision Class 6H thread fit ensures consistent engagement and vibration resistance for long-term fastening integrity
• Standardized dimensions per DIN 439B and ISO 4035 guarantee interchangeability and easy replacement across metric systems
• External hex drive design offers straightforward installation with common tools while maintaining a low-profile appearance
• Full regulatory compliance with RoHS 3 and REACH standards ensures environmental safety and global market acceptance

Professional Applications & Engineering Value

This M6 left hand thin hex nut delivers critical engineering solutions where standard right-hand threads would compromise safety and performance. The 316 stainless steel composition provides exceptional resistance to chloride-induced stress corrosion cracking, making it indispensable for marine equipment, chemical processing systems, and coastal infrastructure. The 1mm coarse pitch thread combined with Class 6H tolerance ensures rapid assembly while maintaining vibration resistance in high-rotation applications like pump shafts, mixer assemblies, and conveyor systems. The thin hex profile (3.2mm height) addresses space-constrained designs without sacrificing the full bearing surface of standard hex nuts, while the left-hand thread direction provides failsafe protection against rotational loosening in counter-clockwise moving components.

Specification Summary & Compliance

Manufactured to DIN 439B and ISO 4035 dimensional standards with Class 6H thread fit tolerance for precision engagement. Features M6 x 1mm coarse left-hand metric threading with 10mm width across flats and 3.2mm height. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no substances of very high concern above threshold limits.
