Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and reducing maintenance frequency.
- Exceptional holding power and vibration resistance due to the Class 3A thread fit and fine thread spacing, ensuring a secure, long-lasting lock. li>High-strength durability backed by a Rockwell B80 hardness, providing reliable performance under mechanical stress.
- Streamlined, headless design allows for flush mounting in applications where space is limited and a smooth surface is required.
- Secure and efficient installation with a 1/8" hex drive, offering high torque transmission and reducing the risk of tool slippage.
- Precise, non-marring contact from the flat tip, which distributes pressure evenly to protect sensitive shaft surfaces.
- Guaranteed reliability and interchangeability through compliance with the stringent ASME B18.3 standard.
Professional Applications & Engineering Value
This 1/4"-28 UNF Class 3A set screw is engineered to solve critical challenges in precision assembly and motion control systems. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it a dependable choice for industrial equipment, automotive components, and outdoor machinery. Its fine thread spacing and Class 3A thread fit create a tighter, more precise engagement, which is crucial for preventing loosening in high-vibration environments. The headless, hex drive design and flat tip allow for a clean, flush finish that is essential in pulleys, gears, and collars, ensuring smooth operation and protecting costly components from damage during securement.
