- Secure anti-loosening performance with left-hand threading that resists rotational forces in specific machinery setups
- Quick and easy installation with coarse UNC threads that reduce assembly time and prevent cross-threading
- Precise thread engagement through Class 2B thread fit, providing consistent clamping force and vibration resistance
- Durable corrosion resistance with steel material offering long-term reliability in industrial environments
- Standard external hex drive allows for use with common tools, simplifying maintenance and replacement procedures
- Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries
Professional Applications & Engineering Value
This Grade 5 steel left hand hex nut with 1 1/8"-7 UNC coarse thread delivers critical engineering solutions where reverse-threading applications prevent accidental loosening from rotational forces. The heavy-duty construction and Class 2B thread fit ensure vibration resistance in machinery, conveyor systems, and rotating equipment where standard right-hand threads would compromise safety. The coarse thread design provides faster assembly in field maintenance situations while maintaining structural integrity under extreme loads. Manufactured from industrial-grade steel with external hex drive compatibility, this fastener meets the demands of manufacturing, automotive, and heavy equipment industries requiring reliable left-hand threading solutions.
Specification Summary & Compliance
This hex nut features 1 1/8"-7 UNC coarse threads with Class 2B thread fit for precise dimensional accuracy. The standard hex profile measures 1 11/16" across flats with 31/32" height. Manufactured to Grade 5 strength specifications and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards for industrial fastener applications.
