Professional Applications & Engineering Value
Engineered for industrial assembly applications requiring reliable fastening performance, these 5-40 UNC coarse thread screws deliver exceptional value in machinery, equipment manufacturing, and structural assemblies. The zinc-plated steel construction provides essential corrosion protection for environments where moisture or chemical exposure is a concern. The combination of 60,000 psi tensile strength and Rockwell B70 hardness ensures the screws maintain clamping force under vibration and dynamic loads, preventing joint failure in critical applications. The fully threaded design with Class 2A thread fit allows for precise torque control and consistent clamping force distribution, while the coarse UNC threading facilitates rapid assembly in production environments. The rounded pan head with Phillips drive offers both aesthetic appeal and practical installation efficiency for various industrial fastening requirements.
Specification Summary & Compliance
These screws feature precision 5-40 UNC coarse threads with Class 2A thread fit tolerance for consistent performance. Manufactured to ASME B18.6.3 specifications, they ensure dimensional accuracy and interchangeability. The products are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications requiring strict regulatory adherence.
