S-92308A636 3/8"-16 x 2 1/2" ASME B18.6.2 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
• Exceptional holding power provided by the coarse UNC thread and Rockwell B80 hardness, preventing component slippage under high stress.
• Precise and secure installation enabled by the Class 2A thread fit, ensuring consistent engagement and reducing the risk of cross-threading.
• High-torque application capability from the external square drive and square head design, allowing for a firm grip with standard tools.
• Effective component fixation due to the cup tip, which concentrates pressure for a strong bite into the mating surface.
• Compliance with major industrial standards including ASME B18.6.2, ensuring dimensional accuracy and interchangeability.
• Safe for regulated industries as it is RoHS 3 and REACH compliant, meeting strict environmental and safety directives.

Professional Applications & Engineering Value

This heavy-duty square head set screw is engineered to address critical challenges in machinery assembly and power transmission systems. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for outdoor, marine, or chemically exposed applications. The coarse 3/8"-16 UNC thread and Class 2A fit offer rapid installation and reliable fastening in soft or hard materials, reducing assembly time while maintaining high clamp load. The square head and external square drive allow for high torque application without stripping, which is essential for set screws that require significant preload to secure gears, pulleys, and collars on shafts. Its cup tip design ensures a concentrated point of contact, minimizing component movement and vibration loosening in dynamic industrial environments.
