S-99183A620 M14 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance through top-lock distorted thread design that maintains clamp force in high-shock environments
• Exceptional strength performance with Class 10 rating, ensuring reliable performance under heavy loads and stress conditions
• Enhanced corrosion protection from black phosphate steel coating that withstands industrial environments and extends service life
• Precise thread engagement with Class 6H thread fit for consistent installation and reduced risk of cross-threading
• Easy installation and removal using standard metric wrenches with the external hex drive design
• Regulatory compliance assurance meeting both RoHS 3 and REACH standards for safe industrial use
• Reliable locking performance with right-hand metric coarse threads (M14x2mm) that provide secure fastening in vibrating machinery

Professional Applications & Engineering Value

This Class 10 M14 locknut delivers critical vibration resistance for demanding industrial applications where loosening under dynamic loads poses significant safety risks. The distorted thread locking mechanism creates consistent interference along the mating bolt threads, eliminating the need for secondary locking devices and reducing assembly time. Manufactured from black phosphate coated steel, this metric hex locknut provides excellent corrosion resistance in harsh environments while maintaining the structural integrity required for heavy machinery, automotive assemblies, and construction equipment. The Class 6H thread fit ensures precise engagement with standard M14x2mm bolts, preventing galling and ensuring consistent clamping force throughout the fastener's service life.

Specification Summary & Compliance

This metric distorted thread locknut features M14x2mm coarse threads with Class 6H thread fit tolerance and standard hex profile (22mm width, 14mm height). Manufactured to Class 10 strength rating with top-lock distorted thread design. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards for industrial applications.
