Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 2-56 UNC rounded pan head Phillips machine screws deliver critical performance advantages where corrosion resistance and mechanical reliability are paramount. The passivated 18-8 stainless steel construction effectively resists oxidation and chemical degradation in manufacturing, electronics, and marine applications. The combination of coarse UNC threading and Class 2A thread fit ensures rapid installation and secure fastening in vibration-prone equipment, while the fully threaded design maximizes load distribution across the entire engagement length. These screws solve common engineering challenges including galvanic corrosion, thread stripping, and assembly inefficiency, making them ideal for precision instruments, control panels, and machinery requiring RoHS/REACH compliant fasteners with consistent dimensional accuracy.
Specification Summary & Compliance
This machine screw maintains Class 2A thread fit tolerance with UNC coarse threading (2-56 size) and complies with ASME B18.6.3 manufacturing specifications. The product is fully certified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to international environmental and safety standards for industrial components.
