- Reliable reusability with consistent locking performance across multiple installation cycles
- High-strength steel construction meeting ASTM Grade C specifications for demanding industrial applications
- Easy installation and removal with standard 7/16" external hex drive compatible with common tools
- Precise thread engagement with Class 2B fit ensuring smooth assembly and consistent torque values
- Environmental compliance with RoHS 3 and REACH regulations for global manufacturing applications
- Optimized coarse thread design (1/4"-20 UNC) providing excellent resistance to loosening under dynamic loads
Professional Applications & Engineering Value
This distorted thread locknut delivers exceptional engineering value by solving critical vibration-induced loosening problems in industrial machinery, automotive systems, and heavy equipment. The top lock distortion technology creates controlled interference with mating threads, generating consistent prevailing torque that resists rotational forces without compromising thread integrity. Manufactured from high-strength steel with ASTM Grade C certification, this UNC coarse thread locknut maintains structural integrity under extreme loads while the Class 2B thread fit ensures precise engagement and reliable performance. The external hex drive design accommodates standard wrenches for efficient installation in confined spaces, making it ideal for assembly lines and maintenance applications where vibration resistance and quick service access are equally important.
Specification Summary & Compliance
This 1/4"-20 UNC locknut features precision Class 2B thread fit with right-hand coarse threading and standard hex profile (7/16" width, 7/32" height). Manufactured to ASTM Grade C strength requirements with distorted thread top lock technology. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe use across global industrial applications.
