Professional Applications & Engineering Value
This 7/8"-9 UNC hex head screw, manufactured from premium 316 stainless steel, is engineered to solve critical challenges in corrosive and high-stress environments. Its exceptional material properties provide long-term reliability in industries like chemical processing, marine, and food & beverage, where moisture and chemicals degrade inferior fasteners. The coarse thread (UNC) and Class 2A fit enable rapid, secure installation even in softer materials or where debris is present, reducing assembly time and preventing cross-threading. The external hex drive and robust head design allow for high torque application, ensuring a tight, vibration-resistant connection. This combination of corrosion resistance, high tensile strength, and standardized dimensions per ASME B18.2.1 delivers predictable performance and reduces maintenance cycles in demanding industrial applications.
Specification Summary & Compliance
This screw features a 7/8"-9 UNC thread with a Class 2A thread fit, ensuring dimensional accuracy and interchangeability. It is manufactured to meet the ASME B18.2.1 standard for hex head cap screws. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances for safe use in global markets.
