S-94560A111 M3 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance with Flex-Top locking design that maintains consistent clamping force in high-stress environments
• Exceptional corrosion protection from 18-8 stainless steel construction, ideal for harsh industrial and outdoor applications
• Precision thread engagement with Class 6H thread fit ensuring reliable, consistent performance across multiple installations
• Easy installation and removal with standard external hex drive design compatible with common metric tools
• Optimized for metric systems with M3 coarse thread (0.5 mm pitch) providing quick assembly in production environments
• Environmental compliance assurance meeting both RoHS 3 and REACH standards for global manufacturing requirements
• Compact dimensional profile (5.5mm width × 4.5mm height) for space-constrained applications without sacrificing performance

Professional Applications & Engineering Value

This M3 Flex-Top locknut delivers critical vibration resistance where traditional fasteners fail. The innovative Flex-Top locking technology creates consistent radial pressure along the metric coarse threads, preventing loosening under dynamic loads in machinery, automotive, and electronic assemblies. Manufactured from 18-8 stainless steel, it withstands corrosive environments that compromise ordinary steel fasteners. The external hex drive enables high-torque installation with standard wrenches, while the Class 6H thread fit maintains precision across repeated use cycles. These engineering features combine to reduce maintenance intervals and prevent costly downtime in manufacturing equipment, transportation systems, and industrial controls where reliable thread locking is non-negotiable.

Specification Summary & Compliance

This locknut features M3 metric coarse threads with 0.5 mm pitch and Class 6H thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. The external hex drive (5.5 mm width) provides secure tool engagement, while the 4.5 mm height offers optimal strength-to-weight ratio. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming absence of restricted substances for global market acceptance. The right-hand thread direction and standard hex nut profile ensure compatibility with existing metric fastener systems.
