Professional Applications & Engineering Value
This 3/8"-16 UNC brass hex head screw is engineered to solve critical challenges in demanding environments where corrosion resistance and mechanical strength are paramount. The brass material inherently resists rust and galvanic corrosion, making it perfect for marine, plumbing, and electrical applications. The coarse UNC thread and Class 2A fit provide rapid assembly and reliable holding power in softer materials or where vibration is a concern. Its partially threaded design ensures that the unthreaded shank bears the load effectively, preventing joint loosening. With an external hex drive and robust Rockwell B55 hardness, it withstands high torque during installation, offering a dependable industrial fastener solution that combines longevity with performance.
Specification Summary & Compliance
This screw adheres to precise dimensional standards with a Class 2A thread fit and UNC coarse thread profile (3/8"-16), ensuring compatibility and ease of use. It is manufactured in compliance with the ASME B18.2.1 specification for hex head screws, guaranteeing consistent quality and performance. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for hazardous substances.
