S-97705A474 10-32 x 3/16" QQ-P-35, MS51023-48 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
• Exceptional holding power provided by the Class 3A thread fit, delivering tighter tolerances and more secure fastening than standard fits.
• High-torque installation capability with the hex drive design, allowing for secure tightening and reducing the risk of tool slippage.
• Precise, fine-thread engagement from the 10-32 UNF thread, offering improved adjustment and vibration resistance in assemblies.
• Flush, headless design for applications where a protruding fastener is not permissible, maintaining a clean and unobstructed surface.
• Secure point contact from the cup tip, which helps prevent loosening under dynamic loads and vibration.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global industrial markets.

Professional Applications & Engineering Value

This precision 10-32 UNF set screw is engineered to solve critical challenges in industrial assembly and machinery. The 18-8 stainless steel material provides excellent resistance to oxidation and corrosion, making it ideal for use in demanding environments such as marine, chemical processing, and outdoor equipment. The fine thread and Class 3A thread fit ensure a tight, secure connection that minimizes the risk of loosening from vibration—a common failure point in dynamic systems. The headless design with a hex drive allows for installation in confined spaces where traditional screw heads won't fit, while the cup tip bites into the shaft material to provide superior anti-rotation performance. These features make it a reliable choice for securing collars, gears, and pulleys onto shafts in precision mechanical drives and motion control systems.
