Professional Applications & Engineering Value
This 3-56 UNF socket head cap screw is engineered to solve critical challenges in precision machinery, electronics, and instrumentation. The 18-8 stainless steel material provides excellent resistance to oxidation and many chemicals, preventing failure in corrosive or high-moisture settings. Its fine thread and Class 3A fit deliver superior clamping force and minimize the risk of loosening under dynamic loads or vibration, a common pain point in motor assemblies and control systems. The combination of 70,000 psi tensile strength and Rockwell B70 hardness ensures the fastener maintains integrity in demanding applications, while the compact socket head design is perfect for space-constrained assemblies where a flush or low-profile fastener is required.
Specification Summary & Compliance
This socket head cap screw features a 3-56 UNF fine thread with a Class 3A thread fit for high precision. It is fully threaded and right-hand direction. Manufactured to meet ASME B18.3 specifications, ensuring dimensional accuracy and interchangeability. The product is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and safe for use in various industrial and consumer applications.
