Professional Applications & Engineering Value
This Socket Head Cap Screw is engineered to solve critical fastening challenges in industrial settings. The 18-8 Stainless Steel material offers excellent resistance to oxidation and corrosion, which is vital for machinery and equipment exposed to moisture or chemicals. The Class 3A thread fit on the 6-40 UNC fine thread provides a tighter tolerance than standard fits, reducing backlash and vibration loosening in precision assemblies. Combined with the high 70,000 psi tensile strength and Rockwell B70 hardness, this hex drive screw ensures a reliable, high-strength connection that maintains integrity under stress, making it an ideal choice for automotive, aerospace, and manufacturing applications where failure is not an option.
Specification Summary & Compliance
This screw features a Class 3A thread fit for precision, adhering to the UNC (Unified National Coarse) thread standard. It is manufactured to meet the dimensional and mechanical specifications of ASME B18.3. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in environmentally conscious and regulated industries.
