Professional Applications & Engineering Value
This Grade 8 steel locknut is engineered to address common challenges in industrial settings, such as vibration-induced loosening and space constraints. The steel insert locking type and fine UNF thread work together to create a durable, reusable fastening solution that withstands repetitive stress and harsh conditions. Its thin hex nut profile is ideal for applications where clearance is limited, such as in machinery, automotive assemblies, and structural frameworks. By combining high tensile strength with a Class 2B thread fit, this locknut ensures precise alignment and long-term reliability, reducing maintenance needs and downtime in heavy-duty industrial applications.
Specification Summary & Compliance
This locknut features a 7/8"-14 UNF fine thread with Class 2B thread fit for consistent accuracy and compatibility. It adheres to standard inch system measurements and includes a steel insert locking mechanism for enhanced security. The product is manufactured to meet RoHS 3 (2015/863/EU) compliance, ensuring it is free from hazardous substances and suitable for global industrial use. Dimensions include a width of 1 5/16" and height of 19/32", supporting reliable performance in precision engineering applications.
