Professional Applications & Engineering Value
This 316 stainless steel socket head cap screw is engineered to address critical challenges in demanding industrial settings, such as chemical processing, marine equipment, and food machinery, where exposure to corrosive agents is common. The passivated finish and high Rockwell B70 hardness provide an extra layer of protection against pitting and wear, extending service life and reducing maintenance costs. Its UNC coarse thread and Class 3A thread fit ensure quick, secure fastening in coarse-grained materials, minimizing assembly time while maintaining high clamping force. The combination of 70,000 psi tensile strength and a 1/4" hex drive makes it a reliable choice for heavy-duty applications requiring both strength and ease of installation.
Specification Summary & Compliance
This fastener adheres to UNC thread standards with a Class 3A thread fit for precise dimensional accuracy. It is manufactured from 316 stainless steel with a passivated finish and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global regulatory requirements.
