S-92311A643 7/16"-14 x 3/4" ASME B18.3 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and extended service life
• Exceptional holding power ensured by the Class 3A thread fit, providing tighter tolerances and more reliable fastening
• High mechanical strength from Rockwell B80 hardness, resisting deformation under heavy loads
• Secure, non-slip installation with the hex drive style and 7/32" drive size for easy application of high torque
• Effective grip and minimal component damage thanks to the cup point tip design, which concentrates force for superior resistance to loosening
• Broad industrial compatibility with UNC coarse threads and right-hand direction, facilitating quick assembly and disassembly
• Regulatory peace of mind with compliance to ASME B18.3, RoHS 3, and REACH standards

Professional Applications & Engineering Value

This 7/16"-14 UNC hex headless set screw is engineered to address critical challenges in industrial assembly, where vibration and dynamic loads can compromise joint integrity. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for applications in manufacturing, automotive, and outdoor equipment. The Class 3A thread fit and coarse thread spacing ensure a precise, secure fit that minimizes the risk of stripping and maintains clamping force in high-stress scenarios. The headless design and cup point tip allow for flush mounting and deep biting into the secured material, preventing axial movement without protruding parts. This combination of features delivers reliable performance in pulley systems, shaft collars, and gear assemblies, where consistent torque and positional stability are paramount.
