Professional Applications & Engineering Value
These 4-40 UNC coarse thread screws with Black Oxide Steel construction address critical industrial fastening challenges where corrosion resistance and consistent performance are paramount. The rounded pan head profile combined with Phillips drive creates an optimal balance between installation efficiency and surface clearance requirements. Engineered with fully threaded right-hand design, they provide maximum engagement in machinery assemblies, electronic enclosures, and precision equipment where vibration resistance and reliable clamping force are essential. The coarse UNC threading ensures rapid installation while maintaining Class 2A tolerance for precise fit in high-volume manufacturing environments.
Specification Summary & Compliance
Manufactured to exact inch system dimensions with Class 2A thread fit per UNC standards, these screws deliver consistent dimensional accuracy. The 4-40 thread size with coarse spacing and 11/16" length provides standardized compatibility across industrial applications. Full compliance with ASME B18.6.3 manufacturing specifications ensures mechanical reliability, while RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance confirms environmental safety and material restrictions adherence for global industrial use.
