Professional Applications & Engineering Value
Engineered for demanding industrial applications, these zinc-plated steel rounded head screws provide critical solutions for machinery assembly, structural frameworks, and heavy equipment maintenance. The 5/16"-18 UNC coarse thread design ensures rapid installation while maintaining secure fastening under dynamic loads. With full threading and 60,000 PSI tensile strength, these fasteners distribute stress evenly, preventing point failures in high-vibration environments. The rounded head profile offers a finished appearance while the slotted drive accommodates standard tooling, making them ideal for maintenance operations where accessibility is limited. These characteristics make them particularly valuable in manufacturing, construction, and automotive applications where reliability and corrosion resistance are paramount.
Specification Summary & Compliance
This 2" length screw features precise Class 2A thread fit tolerances and UNC coarse threading (5/16"-18) manufactured to ASME B18.6.3 specifications. The product maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The combination of zinc-plated steel construction and standardized dimensions guarantees consistent performance and interchangeability in professional applications.
