Professional Applications & Engineering Value
This 2-56 UNC machine screw is engineered to address critical fastening challenges in precision assemblies. The cadmium-plated steel offers a robust barrier against oxidation and chemical exposure, making it ideal for electronics, aerospace components, and machinery where corrosion can lead to failure. Its rounded pan head and Phillips drive facilitate smooth, flush installations in confined spaces, reducing assembly time. The coarse thread and Class 2A fit ensure reliable engagement in materials prone to vibration, preventing loosening in dynamic environments. By meeting stringent standards like ASME B18.6.3, it delivers consistent quality for OEM and MRO applications, enhancing product longevity and reducing maintenance costs.
Specification Summary & Compliance
This screw adheres to precise dimensional tolerances, including a Class 2A thread fit per UNC standards, ensuring compatibility and ease of use. It conforms to ASME B18.6.3, Fed. Spec. FF-S-92, QQ-P-416, MS35206-203, and NASM35206 for manufacturing consistency. Additionally, it is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, supporting sustainable and safe industrial practices.
