Professional Applications & Engineering Value
This 3/8"-16 UNC brass rounded head screw is engineered to solve critical challenges in industrial assembly. The brass material provides excellent corrosion resistance, making it a prime choice for marine, plumbing, and electrical components where rust prevention is paramount. The coarse UNC thread and Class 3A fit enable quick assembly and a secure hold in softer materials like wood and plastic, as well as metals, resisting loosening under vibration. The combination of 50,000 psi tensile strength and the low-profile button head with a hex drive ensures that these screws can withstand significant mechanical stress while allowing for installation in tight spaces. This makes them invaluable for machinery, automotive, and consumer durable goods where reliability and a clean finish are required.
Specification Summary & Compliance
This screw adheres to the UNC (Unified Coarse) thread standard with a precise Class 3A thread fit for superior dimensional accuracy. Key specifications include a 3/8"-16 thread size, 1-1/4" length, and a fully threaded design. It is manufactured to be fully compliant with RoHS 3 (2015/863/EU) under exemption 6(c) and REACH (EC 1907/2006), confirming its adherence to strict environmental and safety regulations for industrial use.
