Professional Applications & Engineering Value
This heavy-duty hex head screw in 316 stainless steel is engineered to solve critical challenges in demanding industrial applications. Its UNC coarse thread design ensures rapid installation in structural components, machinery, and equipment assemblies, while the external hex drive accommodates high torque requirements without stripping. The partially threaded configuration concentrates clamping force precisely where needed, preventing joint loosening under dynamic loads. With exceptional resistance to chemicals, saltwater, and extreme temperatures, this screw delivers long-term reliability in marine, chemical processing, and outdoor infrastructure projects where corrosion failure is a primary concern.
Specification Summary & Compliance
This 5/16"-18 UNC hex head screw maintains Class 2A thread tolerances for consistent fit with standard nuts. Manufactured to ASME B18.2.1 dimensional specifications, it ensures interchangeability and reliability in mechanical systems. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted hazardous substances. With a 2 3/4" length and inch system measurements, it meets North American industrial standards for heavy-duty fastening applications.
