• Exceptional load distribution from the extra wide profile design, reducing surface pressure and preventing joint loosening under vibration
• High-strength performance meeting ASTM Grade 2H specifications, ensuring reliable performance in demanding structural applications
• Precision fine threading (1"-14) with Class 2B fit for tighter engagement and improved resistance to vibrational loosening
• Industry-standard compliance with ASME B18.2.2 and ASTM A194, guaranteeing interchangeability and quality assurance
• Enhanced installation efficiency with standard external hex drive and right-hand UNS thread pattern for quick assembly with common tools
• Optimized dimensional stability with 1 5/8" width and 63/64" height providing consistent performance across repeated installations

Professional Applications & Engineering Value

This heavy hex nut delivers critical engineering value in applications where vibration resistance and long-term reliability are paramount. The zinc yellow-chromate plated steel construction provides superior corrosion protection for outdoor infrastructure, industrial machinery, and structural steel connections exposed to moisture and chemicals. The extra wide profile distributes clamping force more effectively than standard hex nuts, reducing the risk of damage to connected materials while maintaining bolt preload in high-vibration environments. With its 1"-14 fine thread and Class 2B thread fit, this fastener ensures precise engagement that resists loosening under dynamic loads, making it ideal for heavy equipment, bridge construction, and power generation applications where safety and durability cannot be compromised.

Specification Summary & Compliance

This heavy hex nut features Class 2B thread fit tolerance for precise engagement and UNS fine threading (1"-14) with right-hand direction. Manufacturing complies with ASME B18.2.2 dimensional standards and ASTM A194 material specifications, with ASTM Grade 2H strength certification. The zinc yellow-chromate plating provides RoHS and REACH compliant corrosion protection. Dimensions include 1 5/8" width and 63/64" height for consistent performance across industrial applications.
