Professional Applications & Engineering Value
This A286 stainless steel hex nut delivers exceptional performance in high-stress environments where corrosion resistance and thread reliability are critical. The 1/4"-20 UNC coarse thread configuration ensures rapid assembly in vibration-prone applications, while the Class 2B thread fit maintains consistent engagement without binding. Engineered for aerospace, chemical processing, and marine applications, the external hex drive provides secure torque transmission using standard tools. The A286 material grade offers enhanced strength retention at elevated temperatures, solving common fastener failure points in thermal cycling conditions while maintaining compliance with industrial safety standards.
Specification Summary & Compliance
Manufactured to precise inch system dimensions (7/16" width × 7/32" height) with Class 2B thread fit tolerance per UNC standards. The right-hand coarse thread (1/4"-20) follows established industrial specifications for compatibility. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and unrestricted use in global markets. The standard hex nut profile maintains interchangeability with existing fastener systems while delivering superior material performance.
