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 provided by the cup point tip design, which bites into mating surfaces to prevent component slippage.
- Precise and reliable fastening ensured by Class 3A thread fit, offering tighter tolerances for high-vibration applications.
- Easy installation and high torque capability with the internal hex drive (0.050"), allowing for secure engagement with standard tools.
- Space-saving headless design that sits flush with or below the surface, perfect for compact assemblies and rotating components.
- Consistent performance and interchangeability guaranteed by compliance with the ASME B18.3 standard.
- Safe for regulated industries as it is RoHS 3 and REACH compliant, meeting strict environmental and safety directives.
Professional Applications & Engineering Value
This 3-56 UNF set screw is engineered to solve critical challenges in precision assembly. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it suitable for applications in machinery, electronics, and outdoor equipment where environmental factors are a concern. The fine thread (UNF) and Class 3A fit ensure a secure, vibration-resistant connection in high-stress scenarios, preventing loosening over time. The hex headless and cup point design allows for deep penetration and a firm grip on shafts, collars, and gears, ensuring components remain accurately aligned. This combination of material durability and mechanical precision delivers reliable performance in demanding industrial applications, reducing maintenance needs and enhancing the longevity of the assembly.
Specification Summary & Compliance
This set screw features a 3-56 UNF thread with a fine thread spacing and a Class 3A thread fit for precise dimensional accuracy. It is manufactured in accordance with ASME B18.3 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets industry standards for performance and environmental safety.
