Professional Applications & Engineering Value
These 10-24 UNC zinc-plated steel rounded head screws are engineered to address common industrial challenges such as corrosion, vibration loosening, and high-stress fatigue. The zinc plating provides a protective barrier against rust and oxidation, making them ideal for outdoor equipment, machinery, and structural assemblies exposed to moisture. The coarse thread and Class 2A fit ensure quick, reliable installation with standard tools, reducing assembly time and minimizing the risk of thread damage. With a 60,000 psi tensile strength and Rockwell B70 hardness, these screws maintain integrity under heavy loads and repetitive stress, offering long-term reliability in automotive, construction, and manufacturing applications where fastener failure is not an option.
Specification Summary & Compliance
These screws feature a Class 2A thread fit per UNC standards, ensuring dimensional accuracy and interchangeability. Manufactured to meet ASME B18.6.3 specifications, they guarantee consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances and adherence to environmental safety standards.
