Professional Applications & Engineering Value

This brass rounded head screw with 3/8"-16 UNC coarse threading addresses critical challenges in industrial applications where corrosion resistance and mechanical strength are paramount. The Class 3A thread fit ensures precise engagement in tapped holes, reducing the risk of cross-threading and providing reliable performance in high-vibration environments. The combination of 50,000 psi tensile strength and Rockwell B55 hardness makes it ideal for heavy-duty assemblies in marine, electrical, and plumbing systems where brass's natural corrosion resistance prevents galvanic reactions. The 7/32" hex drive allows for efficient installation in confined spaces, while the fully threaded design maximizes load distribution across the entire fastener length.

Specification Summary & Compliance

This rounded head screw features 3/8"-16 UNC coarse threads with Class 3A precision fit according to standard inch system specifications. The fastener maintains dimensional accuracy with a 1-3/4" length and fully threaded construction. Manufacturing compliance includes RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and full REACH (EC 1907/2006) compliance, meeting international environmental and safety standards for industrial components.
