Professional Applications & Engineering Value
This 2-56 UNC T6 Torx rounded head screw is engineered to address common industrial challenges such as vibration loosening, corrosion-induced failure, and assembly inefficiency. The 18-8 stainless steel material, combined with a passivated finish, provides exceptional resistance to rust and chemicals, making it suitable for electronics, aerospace, and medical equipment where cleanliness and durability are critical. The T6 Torx drive minimizes tool slippage, allowing for higher torque application and reducing damage to the screw head during installation. With its fully threaded design and Class 3A thread fit, it ensures tight, secure fastening in precision assemblies, reducing maintenance needs and improving overall system reliability in automated and high-stress environments.
Specification Summary & Compliance
This screw adheres to Class 3A thread tolerance for precise fit, with UNC coarse thread spacing and right-hand thread direction. It meets ASME B18.3 manufacturing specifications for dimensional accuracy and performance. Additionally, it is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for use in regulated industries.
