S-93425A230 1/2"-13 Hex Nuts

Key Features & Benefits at a Glance

• Left-hand threading provides secure fastening in applications requiring reverse rotation resistance
• Zinc-plated steel construction offers excellent corrosion protection for extended service life in demanding environments
• Grade 2 strength rating ensures reliable performance for general industrial applications
• Class 2B thread fit guarantees smooth assembly and consistent engagement with mating components
• Coarse UNC threading enables quick installation and reduced cross-threading risks
• Standard hex profile allows for easy installation using common wrench tools
• Environmental compliance meets RoHS 3 and REACH standards for safe usage across industries

Professional Applications & Engineering Value

These left-hand thread hex nuts are specifically engineered for applications where standard right-hand threading would loosen under counter-clockwise rotational forces. The zinc-plated steel construction provides essential corrosion resistance in industrial settings, while the coarse UNC threading ensures reliable performance in high-vibration environments common in machinery, automotive, and construction equipment. The external hex drive design allows for high torque application using standard tools, making them ideal for maintenance and assembly operations where reverse-threaded fasteners are required to prevent accidental disassembly.

Specification Summary & Compliance

This 1/2"-13 UNC hex nut features Class 2B thread fit tolerance for precise mating with corresponding bolts. Manufactured to inch system standards with dimensions of 3/4" width and 7/16" height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across various industrial applications while meeting Grade 2 mechanical property requirements.
