• Simplified and faster installation with coarse UNC threads and Class 2A fit for easy starting and engagement
• Optimized for demanding applications featuring a partially threaded design for precise clamping where needed
• Guaranteed dimensional consistency and interchangeability, manufactured to meet ASME B18.2.1 specifications
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental directives

Professional Applications & Engineering Value

This 3/4"-10 UNC Hex Head Screw is engineered from 316 Stainless Steel to solve critical challenges in corrosive and high-strength environments. The material's superior resistance to chemicals and saltwater makes it ideal for marine equipment, chemical processing plants, and offshore structures. The coarse UNC thread and Class 2A thread fit ensure quick, reliable assembly even in dirty or high-vibration settings, reducing installation time and preventing cross-threading. With a partially threaded shank, it provides unthreaded grip length for better joint integrity, while the external hex drive and large head width allow for high torque application with standard tools. This combination of high tensile strength and corrosion resistance delivers long-term reliability, minimizing maintenance and replacement costs in industrial fastening applications.
