S-90494A237 7/8"-14 Hex Nuts

Key Features & Benefits at a Glance

• Reduced weight and material usage thanks to the thin profile design while maintaining full thread engagement
• Superior vibration resistance in dynamic applications due to the fine UNF thread pitch
• Reliable and consistent fit with mating components ensured by the precision Class 2B thread fit
• High durability and dependable strength for general-purpose industrial use provided by the Grade 2 steel construction
• Easy installation and removal with standard tools facilitated by the external hex drive design
• Compliance with strict environmental regulations for safe and responsible sourcing, meeting RoHS 3 and REACH standards
• Broad compatibility with inch-system components and right-hand threaded fasteners commonly used in North American machinery

Professional Applications & Engineering Value

This 7/8"-14 UNF thin hex nut is engineered to address critical needs in assembly and maintenance where space and weight are considerations without compromising on strength. The Grade 2 steel construction provides excellent toughness for a wide range of industrial applications, from machinery assembly to automotive fixtures. Its fine UNF threads and Class 2B fit offer superior resistance to loosening under vibration, a common failure point in dynamic systems. The thin profile allows for use in confined spaces where a standard hex nut would not fit, solving clearance issues in complex assemblies. The external hex drive ensures straightforward installation with common wrenches, streamlining production and maintenance workflows while the right-hand thread direction maintains compatibility with standard bolt configurations.

Specification Summary & Compliance

This nut conforms to the Unified National Fine (UNF) thread standard with a Class 2B thread fit, ensuring dimensional accuracy and interchangeability. The manufacturing adheres to the inch system with a thread size of 7/8"-14. It is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances. The fastener meets the mechanical properties for Grade 2 strength classification, suitable for a wide range of general engineering applications.
