Professional Applications & Engineering Value
This alloy steel set screw delivers exceptional engineering value in industrial applications where vibration resistance and secure fastening are critical. The 3/8"-16 UNC coarse thread configuration with Class 2A fit ensures reliable installation in machinery, automotive components, and power transmission systems where loosening under dynamic loads is a concern. The square head design with external square drive provides superior torque transmission compared to standard fasteners, reducing the risk of stripping during high-torque applications. With Rockwell C45 hardness, this set screw maintains its mechanical properties in harsh environments, making it ideal for heavy-duty equipment, manufacturing fixtures, and industrial assemblies requiring permanent or semi-permanent fastening solutions.
Specification Summary & Compliance
This set screw features precise Class 2A thread fit tolerances according to UNC standards, ensuring consistent thread engagement and reliable performance. Manufacturing complies with ASME B18.6.2 specifications for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for use in environmentally conscious industrial applications worldwide.
