Key Features & Benefits at a Glance
- Superior vibration resistance with integrated spring lock washer to prevent loosening in high-stress applications
- Enhanced durability and corrosion protection through black-oxide steel construction for extended service life
- Heavy-duty performance with Class 8 strength rating, ensuring reliable performance under high loads
- Precision thread engagement with Class 6H metric coarse threads for secure, consistent fastening
- Easy installation and removal using standard external hex drive tools, reducing assembly time
- Comprehensive compliance with REACH and RoHS 3 environmental standards for safe industrial use
- Optimized dimensions (10mm width, 6.6mm height) with 14mm washer OD for stable mounting surfaces
Professional Applications & Engineering Value
This M6 x 1 mm Class 8 black-oxide steel locknut delivers exceptional engineering value in demanding industrial environments where vibration-induced loosening compromises assembly integrity. The integrated spring lock washer creates constant tension that counters rotational forces, making it ideal for automotive components, machinery frames, and electrical enclosures subject to continuous motion. The metric coarse threading (1mm pitch) combined with Class 6H thread fit ensures rapid installation while maintaining precise tolerance control. The black-oxide surface treatment provides corrosion resistance without compromising dimensional stability, while the external hex drive accommodates standard wrenching tools for efficient maintenance cycles in production facilities and equipment servicing.
Specification Summary & Compliance
This metric hex locknut features M6 x 1mm coarse right-hand threads with Class 6H thread fit tolerance, 10mm width across flats, and 6.6mm height. The assembly includes a steel spring lock washer with 14mm outer diameter. Manufactured to Class 8 strength rating standards and fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives for industrial applications.
