Professional Applications & Engineering Value
This 4-48 UNF Socket Head Cap Screw is engineered to solve critical fastening challenges in precision industries. The 18-8 Stainless Steel material provides excellent corrosion resistance, making it suitable for applications exposed to moisture, chemicals, or outdoor elements. Its Class 3A fine thread ensures a precise, reliable fit in tapped holes, reducing the risk of vibration loosening in machinery, electronics, and aerospace components. The socket head design with a 3/32" hex drive allows for high-torque installation without slippage, which is essential for maintaining assembly integrity in compact or high-stress environments. These features make it an ideal choice for OEMs and maintenance teams requiring durable, high-strength industrial fasteners that perform consistently under demanding conditions.
Specification Summary & Compliance
This screw adheres to ASME B18.3 specifications, ensuring dimensional accuracy and interchangeability. The Class 3A thread fit provides tight tolerances for precision assemblies, while the UNF fine thread (4-48) offers superior holding power. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming it is free from hazardous substances and meets stringent environmental and safety standards for global industrial use.
