S-90730A513 0-80 Hex Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance from Black-Oxide coated 18-8 Stainless Steel, ideal for harsh environments and extending service life.
• Precise, reliable fastening ensured by the Class 2B thread fit, minimizing the risk of cross-threading and ensuring consistent clamping force.
• Fine thread design (UNF) provides a higher number of threads per inch, offering improved vibration resistance and a more secure hold in delicate assemblies.
• Compact, narrow profile allows for installation in tight spaces where standard hex nuts cannot fit, enhancing design flexibility.
• External hex drive facilitates easy installation and removal with common tools, streamlining assembly and maintenance processes.
• Compliance with major regulations including RoHS 3 and REACH, ensuring safety and environmental responsibility for global supply chains.
• Right-hand thread direction for standard, intuitive installation compatible with most common industrial applications.

Professional Applications & Engineering Value

This 0-80 UNF fine thread hex nut is engineered to address critical challenges in precision assemblies, particularly in electronics, instrumentation, and aerospace sectors where space is limited and reliability is non-negotiable. The Black-Oxide 18-8 Stainless Steel construction provides a robust barrier against oxidation and chemical exposure, preventing fastener failure in corrosive conditions. Its narrow profile and fine UNF threads deliver superior vibration resistance, maintaining joint integrity in high-stress environments. By combining a Class 2B thread fit with an external hex drive, these nuts ensure quick, error-free installation, reducing assembly time and improving overall equipment durability for demanding industrial applications.

Specification Summary & Compliance

This hex nut features a 0-80 UNF fine thread with a Class 2B fit, ensuring dimensional accuracy and interchangeability per unified screw thread standards.
