S-95140A123 5/16"-24 Hex Nuts

Key Features & Benefits at a Glance

• Exceptional Strength & Reliability: Made from Grade 5 steel, this nut provides high tensile strength for secure, vibration-resistant fastening in demanding industrial environments.
• Secure Left-Hand Threading: The left-hand UNF fine thread (5/16"-24) is engineered for applications where standard right-hand rotation could loosen the assembly, offering enhanced safety.
• Precise Thread Fit: Class 2B thread fit ensures consistent engagement and smooth assembly, reducing the risk of cross-threading and improving installation efficiency.
• Durable & Corrosion-Resistant: The steel construction provides excellent durability and resistance to wear, ensuring long-term performance under various operational stresses.
• Standard External Hex Drive: The standard 1/2" hex profile allows for easy installation and removal with common wrenches, streamlining maintenance and assembly processes.
• Environmental Compliance: Compliant with RoHS 3 and REACH regulations, making it suitable for use in industries with strict environmental and safety standards.
• Fine Thread Advantage: The UNF fine thread offers a higher number of threads per inch, resulting in better adjustment precision and improved load distribution compared to coarse threads.

Professional Applications & Engineering Value

This Grade 5 steel left-hand hex nut is specifically designed for applications where reverse rotation is a critical factor, such as in rotating machinery, automotive components, and equipment with left-hand threaded shafts. The UNF fine thread (5/16"-24) and Class 2B fit ensure precise alignment and reduce the likelihood of loosening under dynamic loads, addressing common issues like vibration-induced failure. Its external hex drive facilitates straightforward installation in confined spaces, while the robust steel material provides the necessary strength for high-stress environments, making it an ideal choice for industrial fastening solutions that demand reliability and compliance with modern environmental standards like RoHS and REACH.

Specification Summary & Compliance
