Professional Applications & Engineering Value
This Socket Head Cap Screw is engineered to address common challenges in precision machinery, automotive, and heavy equipment assembly. The 18-8 Stainless Steel material provides inherent resistance to rust and chemical exposure, making it suitable for outdoor or corrosive settings. Its UNC coarse threads and Class 3A fit ensure quick assembly with minimal cross-threading risk, while the vented feature is critical in applications requiring pressure management, such as hydraulic systems or sealed enclosures. The combination of high tensile strength and Rockwell B70 hardness guarantees that the screw maintains clamp load under dynamic stresses, reducing maintenance needs and enhancing operational reliability in demanding industrial fastening scenarios.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a Class 3A thread fit for precise dimensional accuracy. It features a 1/4"-20 thread size, 3/4" length, and right-hand thread direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in regulated industries.
