Professional Applications & Engineering Value
These 2-56 UNC pan head screws deliver critical performance in precision assemblies where corrosion resistance and mechanical reliability are paramount. The passivated 18-8 stainless steel material effectively resists oxidation and chemical exposure, extending service life in electrical enclosures, instrumentation, and automated machinery. The coarse UNC thread and Class 2A fit ensure rapid installation and maintain clamp load under dynamic stresses, while the Phillips drive accommodates high-torque applications without stripping. Fully threaded for uniform stress distribution, these industrial screws are engineered to prevent loosening in vibrating environments, making them ideal for machine screws applications in manufacturing, aerospace, and electronics sectors.
Specification Summary & Compliance
Manufactured to exact ASME B18.6.3 specifications, these screws feature a Class 2A thread fit with UNC coarse threading (2-56 size, 0.086" diameter) and are fully threaded with a 3/16" length. The Rockwell B70 hardness and 70,000 psi tensile strength ensure dimensional stability under load. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming adherence to stringent environmental and safety regulations for global industrial use.
