Professional Applications & Engineering Value
These 5-40 UNC zinc-plated steel rounded head screws are engineered to address common industrial challenges, such as corrosion and mechanical stress. The zinc plating provides a protective barrier against rust and oxidation, extending service life in demanding settings like machinery assembly, electrical enclosures, and automotive components. With a coarse thread and Class 2A fit, they offer quick, secure fastening in materials where vibration resistance is critical. The pan head style and Phillips drive facilitate easy installation with standard tools, reducing labor costs and improving efficiency in high-volume production lines. Fully threaded for maximum engagement, these screws ensure robust connections in applications requiring high tensile strength and durability.
Specification Summary & Compliance
This product features precise Class 2A thread fit per UNC standards, with a thread size of 5-40 and coarse spacing for reliable performance. Dimensions include a 7/16" length, 0.125" thread diameter, and pan head profile. It complies with ASME B18.6.3 for manufacturing consistency, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are adhered to.
