Professional Applications & Engineering Value
Engineered for precision, this 2-56 UNC nylon hex head screw solves critical challenges in electrical and electronic assemblies. The black nylon plastic material inherently resists corrosion, eliminating galvanic issues and making it suitable for sensitive equipment. Its coarse UNC thread and Class 2A fit ensure quick, reliable installation with reduced cross-threading risks, speeding up production lines. The fully threaded design and external hex drive offer superior clamping force and tool accessibility, which is vital in confined spaces. Operating reliably from -40° to 185° F, this screw maintains integrity in fluctuating thermal environments, providing long-term durability for control panels, communication devices, and consumer electronics where non-conductivity and RoHS compliance are mandatory.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. Key specifications include a #2-56 thread size, 0.086" thread diameter, 7/16" length, and right-hand thread direction. It is manufactured to be fully threaded and is RoHS 3 (2015/863/EU) Compliant, meeting stringent environmental and safety regulations for global industrial use.
