Key Features & Benefits at a Glance
- Superior corrosion resistance from brass material, ideal for harsh environments and reducing replacement frequency
- High tensile strength of 50,000 PSI ensures reliable load-bearing capacity for demanding industrial applications
- Class 2A thread fit provides smooth assembly and consistent engagement, minimizing cross-threading risks
- Coarse UNC threading offers faster installation and better performance in softer materials or high-vibration settings
- External hex drive with 15/16" head width allows for high-torque application using standard tools, enhancing installation efficiency
- Fully threaded 1" length design maximizes grip and clamping force across the entire fastener
- Rockwell B55 hardness balances durability with machinability, resisting wear while maintaining structural integrity
Professional Applications & Engineering Value
This 5/8"-11 UNC brass hex head screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and assembly efficiency. The brass material inherently resists rust and galvanic corrosion, making it suitable for marine, plumbing, and electrical applications where moisture exposure is a concern. Its coarse UNC thread and Class 2A fit ensure quick, secure fastening in materials like soft metals or plastics, reducing installation time while maintaining joint integrity. The external hex drive design accommodates high torque for heavy-duty connections, providing reliable performance in machinery, construction, and automotive assemblies where strength and environmental durability are critical.
Specification Summary & Compliance
This screw adheres to ASME B18.2.1 dimensional standards, with a Class 2A thread fit ensuring precise tolerances for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances. The specifications include a 5/8"-11 UNC coarse thread, 1" length, and 50,000 PSI tensile strength, meeting rigorous industrial requirements for reliability and safety.
