S-92311A623 3/8"-16 x 7/8" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Exceptional holding power and vibration resistance from the Class 3A thread fit, ensuring a secure, reliable fastening in demanding applications.
• High-strength durability provided by Rockwell B80 hardness, resisting wear and deformation under heavy loads.
• Easy installation and removal with the 3/16" hex drive, allowing for high-torque application in confined spaces where a headless design is required.
• Effective grip and component positioning thanks to the cup point tip, which bites into the mating surface to prevent slippage.
• Broad compatibility with the standard 3/8"-16 UNC coarse thread, facilitating quick assembly and interchangeability.
• Compliance with major industry standards including ASME B18.3, ensuring consistent quality, reliability, and performance.

Professional Applications & Engineering Value

This 3/8"-16 UNC Class 3A stainless steel set screw is engineered to solve critical challenges in machinery assembly, automotive components, and precision equipment. The headless design with a hex drive is perfect for applications where space is limited and a flush surface is necessary. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for use in demanding environments, including those exposed to moisture or chemicals. The coarse UNC threads and Class 3A fit ensure a tight, secure connection that resists loosening under vibration, a common issue in dynamic industrial settings. The cup point tip offers superior biting action into shafts and hubs, preventing rotational movement and maintaining precise alignment. This combination of features delivers reliable performance, reduces maintenance needs, and enhances the longevity of assembled components.
