Professional Applications & Engineering Value
Engineered for industrial and marine settings, these 8-32 UNC 316 stainless steel slotted screws address critical challenges like corrosion, high stress, and regulatory requirements. The passivated finish significantly enhances the innate corrosion resistance of 316 stainless steel, making these rounded head screws suitable for equipment exposed to moisture, chemicals, and saltwater. The coarse thread (UNC) and Class 2A fit facilitate quick, reliable installation in metals and plastics, reducing assembly time while maintaining joint integrity. With a 100,000 psi tensile strength, they provide dependable performance in structural applications, from machinery assembly to electronic enclosures, ensuring long-term reliability without frequent maintenance or replacement.
Specification Summary & Compliance
This screw adheres to ASME B18.6.3 specifications for dimensional accuracy, featuring UNC coarse threads with a Class 2A thread fit for consistent performance. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance control in industrial supply chains.
