Professional Applications & Engineering Value

These 18-8 Stainless Steel Socket Head Cap Screws provide engineering solutions for demanding industrial applications where corrosion resistance and high tensile strength are critical. The 1/4"-20 UNC coarse threads with Class 3A fit ensure rapid assembly and reliable performance in vibration-prone environments, while the hex socket drive allows for high-torque installation in confined spaces. Ideal for machinery, automotive, and manufacturing equipment, these fully threaded screws distribute clamping force evenly across the entire engagement length, preventing joint failure and maintaining structural integrity under dynamic loads. The combination of 70,000 psi tensile strength and Rockwell B70 hardness makes them suitable for high-stress applications where fastener failure is not an option.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 3A thread fit and UNC coarse thread specifications. Complies with ASME B18.3 manufacturing standards for socket head cap screws, ensuring dimensional accuracy and interchangeability. Meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety. The inch system measurement and standardized thread profile guarantee consistent performance across industrial applications requiring reliable fastening solutions.
