• Maximum holding power achieved through the cup point tip design that digs into surfaces securely
• Precise thread engagement with Class 3A fit ensuring tight, reliable fastening in critical applications
• Easy installation and removal using the 0.035" hex drive, compatible with standard tools
• Enhanced durability from Rockwell B80 hardness, resisting wear and deformation under load
• Broad industrial compatibility with UNC coarse threads and right-hand direction for common machinery
• Regulatory peace of mind with compliance to ASME B18.3, RoHS 3, and REACH standards

Professional Applications & Engineering Value

This 2-56 UNC set screw is engineered to address common industrial fastening challenges, such as component slippage and corrosion-induced failure. The 18-8 stainless steel material provides excellent resistance to rust and chemicals, making it ideal for applications in manufacturing, automotive, and electronics where environmental exposure is a concern. The hex headless design with a cup point tip ensures deep penetration into shafts or hubs, preventing rotational movement in assemblies. With coarse thread spacing and Class 3A thread fit, it offers quick installation and high clamping force, reducing assembly time and maintenance needs in precision equipment and machinery.

Specification Summary & Compliance

This set screw adheres to precise dimensional standards, including a Thread Fit of Class 3A for tight tolerances and UNC thread type with 2-56 size. It meets ASME B18.3 specifications for consistency and reliability. Additionally, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and regulatory adherence for global industrial use.
