S-90923A234 M6 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance through integrated external-tooth lock washer design that maintains secure fastening in high-stress environments
• Enhanced corrosion protection with black-oxide coating on both 18-8 stainless steel nut and 400 stainless steel washer for extended service life
• Reliable thread engagement with Class 6H thread fit ensuring precise mating with compatible bolts and components
• Quick installation efficiency with standard hex profile and coarse 1mm pitch threading for faster assembly in industrial settings
• Dual-material durability combining the strength of 18-8 stainless steel nut with the spring characteristics of 400 stainless steel washer
• Environmental compliance assurance meeting both RoHS 3 and REACH standards for safe use in regulated industries
• Optimized locking performance with 11.5mm OD washer providing maximum surface contact and anti-rotation security

Professional Applications & Engineering Value

This M6 locknut with external-tooth lock washer addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and electrical enclosures. The black-oxide 18-8 stainless steel construction provides exceptional corrosion resistance while the integrated 400 stainless steel washer creates permanent locking action through its tooth design that bites into mating surfaces. The metric coarse threading (1mm pitch) ensures rapid installation without compromising holding power, making it ideal for production lines requiring both speed and reliability. Engineered for Class 6H thread fit, this locking nut solution maintains precise tolerances in applications where thermal cycling and dynamic loads would compromise standard fasteners.

Specification Summary & Compliance

This industrial locknut features M6 x 1mm metric coarse thread with Class 6H thread fit precision, right-hand threading direction, and standard hex drive (10mm width, 6.2mm height). The integrated external-tooth lock washer measures 11.5mm OD and is manufactured from black-oxide 400 series stainless steel. The assembly complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory compliance for international industrial applications.
