- Enhanced durability and corrosion protection with zinc-plated steel construction for extended service life
- Precise Class 2B thread fit ensures smooth installation and reliable engagement with mating components
- Maximum holding power from 1"-14 fine threading that provides more thread contact surface area
- Industry-standard compatibility with UNS thread specifications for broad application use
- Easy installation and removal with standard external hex drive design using common tools
- Regulatory compliance assurance meeting REACH and RoHS 3 environmental standards
Professional Applications & Engineering Value
This Grade 2 zinc-plated steel locknut delivers exceptional performance in high-vibration environments where standard fasteners typically fail. The center lock distorted thread design creates consistent interference along the entire thread path, effectively resisting loosening from shock, vibration, and thermal cycling. The 1"-14 fine thread configuration provides superior load distribution compared to coarse threads, making it ideal for heavy machinery, automotive assemblies, and industrial equipment requiring precise torque retention. The zinc plating offers sacrificial corrosion protection while maintaining electrical conductivity for grounding applications. Engineered for demanding industrial applications, this locknut eliminates the need for secondary locking devices, reducing assembly time and maintenance costs.
Specification Summary & Compliance
This locknut features Class 2B thread fit per UNS standards with 1"-14 fine threading and right-hand thread direction. Manufactured from Grade 2 steel with zinc plating for corrosion resistance. Dimensions include 1-1/2" width and 55/64" height with standard external hex drive. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations for industrial safety standards.
