S-93425A038 1"-8 Hex Nuts

Key Features & Benefits at a Glance

• Left-hand threading provides secure fastening in applications where standard right-hand threads may loosen due to rotational forces.
• Zinc-plated steel construction offers excellent corrosion resistance, extending the nut's service life in demanding industrial environments.
• Grade 2 strength rating ensures reliable performance for a wide range of general-purpose and industrial assembly applications.
• Coarse UNC thread allows for quicker installation and is less prone to cross-threading compared to fine threads.
• Class 2B thread fit provides a consistent, free-running fit with commercial bolts, facilitating faster assembly and disassembly.
• Standard external hex drive offers compatibility with common wrenches and sockets, ensuring easy installation and removal.
• RoHS 3 and REACH compliance guarantees the product meets stringent environmental and safety regulations for global industrial use.

Professional Applications & Engineering Value

This 1"-8 UNC left hand thread hex nut is engineered for applications where counter-clockwise rotation is the operational direction, preventing unintended loosening in machinery such as rotating shafts, mixer blades, and certain power transmission systems. The zinc-plated steel material provides a durable barrier against rust and corrosion, which is critical for maintaining integrity in humid or outdoor industrial settings. The coarse thread design is particularly valuable in environments where vibration, debris, or rapid assembly are concerns, as it resists jamming and allows for more forgiving alignment. Combined with the Class 2B thread fit, this nut ensures a reliable, consistent connection that reduces the risk of assembly errors and downtime, making it an essential industrial fastener for maintenance and production lines.

Specification Summary & Compliance

This hex nut conforms to Unified Coarse (UNC) thread standards with a Class 2B thread fit for consistent dimensional accuracy. The product is manufactured from zinc-plated steel and meets Grade 2 mechanical properties. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of restricted hazardous substances and safe for use in regulated industrial markets.
