Professional Applications & Engineering Value
These 3-48 UNC flat head slotted screws are engineered to address common industrial challenges, such as vibration loosening and material fatigue. The zinc-plated steel material provides a protective barrier against rust and corrosion, making them ideal for machinery, electronics, and outdoor equipment where exposure to moisture is a concern. The coarse UNC thread and Class 2A fit ensure quick, secure fastening in soft metals or plastics, reducing assembly time and improving production efficiency. With a fully threaded design and 82° countersink angle, they offer a low-profile solution for applications requiring smooth surfaces, such as automotive panels or aerospace components, while maintaining high tensile strength for demanding loads.
Specification Summary & Compliance
This product features precise Class 2A thread fit per UNC standards, with a thread size of 3-48 and length of 1/2". It meets ASME B18.6.3 specifications for dimensional accuracy and performance. Additionally, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets.
