Professional Applications & Engineering Value
This Grade 2 zinc-plated steel thin hex nut is engineered to address common industrial challenges, such as corrosion in harsh settings and space limitations in compact assemblies. Its zinc-plated finish provides a protective barrier against rust, extending service life in outdoor or high-humidity applications like machinery, structural frameworks, and automotive components. The 1"-8 UNC coarse thread design facilitates rapid installation, reducing downtime in production lines, while the thin hex profile allows for use where standard nuts are too bulky. With a Class 2B thread fit, it ensures reliable, vibration-resistant connections, making it a versatile choice for maintenance, manufacturing, and construction projects that demand durability and efficiency.
Specification Summary & Compliance
This hex nut adheres to UNC coarse thread standards with a Class 2B thread fit for consistent dimensional accuracy. It meets Grade 2 strength requirements and is manufactured from zinc-plated steel, with a width of 1-1/2" and height of 35/64". The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
