S-92311A406 3/4"-10 x 3" 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 reducing long-term maintenance costs.
• Exceptional holding power ensured by the Class 3A thread fit, providing a tighter, more secure and vibration-resistant connection.
• High-strength durability with a Rockwell B80 hardness, offering reliable performance under significant mechanical stress.
• Secure and easy installation using the 3/8" hex drive, allowing for high torque application without slippage.
• Effective component positioning with the cup tip design, which bites into the shaft for a non-slip, permanent setting.
• Reliable coarse threading (UNC) for faster installation and robust performance in a wide range of industrial materials.
• Comprehensive compliance with ASME B18.3, RoHS, and REACH, guaranteeing quality, safety, and environmental standards.

Professional Applications & Engineering Value

This 3/4"-10 UNC Class 3A set screw is engineered to solve critical challenges in machinery assembly and component fixation. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it indispensable in demanding environments like food processing, marine applications, and outdoor equipment. Its headless design and hex drive allow for flush mounting and secure installation in confined spaces, preventing accidental disengagement. The coarse UNC thread and Class 3A fit ensure a precise, tight grip on pulleys, gears, and collars, effectively resisting loosening under high vibration and torque. The cup tip concentrates force for a firm bite, offering superior axial holding power compared to standard points, which is vital for permanent positioning in high-stress industrial applications.
