Professional Applications & Engineering Value
This zinc-plated steel slotted rounded head screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and high-stress demands. The UNC coarse thread pattern provides excellent grip in softer materials and resists stripping, while the fully threaded design ensures uniform load distribution for enhanced joint integrity. With a tensile strength of 60,000 psi and Rockwell B69 hardness, it withstands heavy-duty applications in machinery, electronics, and automotive sectors. The rounded head minimizes snagging and improves safety, making it ideal for assemblies requiring smooth surfaces and reliable fastening under dynamic conditions.
Specification Summary & Compliance
This screw features precise Class 2A thread fit and adheres to ASME B18.6.3 standards for dimensional accuracy and performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met. The UNC coarse thread with right-hand direction and standard rounded head profile guarantees consistent manufacturing quality for industrial use.
