Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 316 stainless steel socket head cap screws deliver exceptional performance where corrosion resistance and mechanical reliability are paramount. The passivated finish enhances surface durability while maintaining the material's inherent resistance to chlorides and chemical exposure. Featuring 4-40 UNC coarse threads with Class 3A precision fit, these fasteners ensure consistent clamping force in machinery, marine equipment, and chemical processing applications. The hex socket drive design allows for high-torque installation in confined spaces, while the partial threading provides optimal stress distribution across connected components. These characteristics make them ideal for critical assembly applications requiring long-term reliability under dynamic loading conditions.
Specification Summary & Compliance
This socket head cap screw maintains inch system dimensions with precise Class 3A thread fit according to UNC standards, ensuring interchangeability and reliable performance. The fastener meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, confirming its suitability for regulated industrial markets. Manufacturing specifications include 70,000 psi tensile strength, Rockwell B70 hardness, and controlled partial threading with minimum 3/4" thread length on the 1" overall fastener.
