Professional Applications & Engineering Value
This 5/16"-18 x 6" 18-8 Stainless Steel Hex Head Screw is engineered to address critical challenges in industrial settings, such as corrosion-induced failure and vibration loosening. The UNC coarse thread design ensures rapid installation and secure holding power in materials like metal and wood, while the partial threading offers a non-threaded section that enhances shear strength and prevents joint slippage. With an external hex drive and hex head, it allows for high-torque application using standard tools, making it ideal for machinery, structural frameworks, and assembly lines. The 18-8 stainless steel material provides excellent resistance to rust and chemicals, extending service life in demanding environments. Fully compliant with ASME B18.2.1, this screw delivers consistent performance, reducing maintenance costs and downtime for B2B clients.
Specification Summary & Compliance
This hex head screw features precise Class 2A thread fit and UNC coarse threading (5/16"-18 thread size) with a minimum thread length of 7/8" and overall length of 6". It meets ASME B18.2.1 manufacturing specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industry-standard quality.
