Professional Applications & Engineering Value
This 5/16"-18 UNC hex head screw in 316 stainless steel is engineered to address common industrial challenges, such as corrosion in aggressive settings like chemical processing, marine, and outdoor installations. The coarse thread and Class 2A fit provide reliable engagement in softer materials or where vibration resistance is critical, reducing the risk of loosening. With a fully threaded right-hand design and external hex drive, it simplifies assembly in tight spaces, while the high tensile strength and hardness ensure it withstands heavy loads and repetitive stress. Ideal for machinery, structural frameworks, and equipment exposed to moisture or chemicals, this fastener delivers long-term reliability and minimizes maintenance needs in industrial applications.
Specification Summary & Compliance
This product features precise Class 2A thread fit with UNC coarse threading (5/16"-18), ensuring dimensional accuracy per ASME B18.2.1 standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming adherence to environmental and safety regulations for industrial use.
