Professional Applications & Engineering Value
This 3-48 UNC brass rounded head screw is engineered to address critical challenges in precision assemblies. Its brass material provides inherent corrosion resistance, making it a reliable choice for electrical components, marine equipment, and plumbing systems where moisture and chemicals are present. The Class 3A thread fit and coarse UNC threading deliver superior holding power and reduce the risk of cross-threading during high-speed installation. The button-style rounded head with a 1/16" hex drive offers a low-profile, flush finish while allowing for high torque application without cam-out. This combination ensures long-term performance in industrial fastening applications, from machinery to consumer electronics, where durability and regulatory compliance are paramount.
Specification Summary & Compliance
This fastener adheres to UNC coarse thread standards with a precision Class 3A thread fit for tight tolerances. It is manufactured to meet RoHS 3 (2015/863/EU) compliance under exemption 6(c) for lead in copper alloy and is fully REACH (EC 1907/2006) compliant, ensuring it meets the latest environmental and safety regulations for industrial use.
