Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and reducing maintenance costs
- Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for reliable performance under high stress
- Precise thread engagement with Class 3A fit and 9/16"-18 UNF fine threads, ensuring secure fastening and vibration resistance
- Optimized torque transmission via the 7/16" hex drive and standard socket head profile, minimizing cam-out and tool wear
- Versatile partial threading on a 6" length provides a non-threaded shank for precise alignment and shear strength
- Long-term reliability with compliance to ASME B18.3, guaranteeing dimensional accuracy and interchangeability
- Environmental and safety assurance through RoHS 3 and REACH compliance, meeting strict regulatory standards
Professional Applications & Engineering Value
This 18-8 stainless steel socket head cap screw is engineered to solve critical challenges in demanding industrial settings. Its corrosion-resistant material prevents degradation in moist or chemical environments, while the 70,000 psi tensile strength and Class 3A UNF fine thread ensure a secure, vibration-resistant connection in heavy machinery, automotive assemblies, and precision equipment. The partially threaded 6" design allows the unthreaded shank to bear shear loads, reducing thread wear and improving joint integrity. With a 7/16" hex drive, it enables high-torque installation without stripping, making it a reliable choice for high-stress applications where failure is not an option.
Specification Summary & Compliance
This socket head cap screw adheres to Class 3A thread fit for precise tolerance and a 9/16"-18 UNF fine thread profile. Manufacturing conforms to ASME B18.3 specifications, ensuring dimensional consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances.
