Key Features & Benefits at a Glance
- Superior corrosion resistance from 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
- Precise thread engagement with Class 2B fine threads for secure, vibration-resistant connections in critical assemblies.
- Full threading design allows maximum adjustability and uniform load distribution across the entire nut length.
- ASTM A582 compliance guarantees material quality and consistent mechanical performance for industrial applications.
- Standard UNF fine thread profile provides excellent sealing capability and reduced loosening under dynamic loads.
- Environmental regulation compliance with RoHS 3 and REACH standards for safe global supply chain integration.
- Optimized 1" length and 23/64" OD delivers ideal strength-to-weight ratio for space-constrained installations.
Professional Applications & Engineering Value
This 18-8 stainless steel coupling nut solves critical challenges in precision assembly systems where corrosion resistance and thread reliability are paramount. The fully threaded UNF fine thread configuration maintains consistent clamping force in vibrating equipment, while the Class 2B thread fit ensures smooth mating with corresponding male threads without binding. Engineers specify this ASTM A582 compliant component for hydraulic systems, aerospace fittings, and marine hardware where environmental compliance and material traceability are required. The right-hand thread direction provides standardized installation across maintenance protocols, reducing assembly errors in high-volume production environments.
Specification Summary & Compliance
Manufactured to ASTM A582 specifications with Class 2B thread fit tolerance for unified fine threads (1/4"-28 UNF). The 18-8 stainless steel construction meets industry standards for corrosion resistance and mechanical properties. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for hazardous substance restrictions. Dimensions include 1" length and 23/64" OD with right-hand thread orientation.
