Professional Applications & Engineering Value
These zinc-plated steel rounded head screws deliver exceptional engineering value across industrial applications where corrosion resistance and structural integrity are paramount. The UNC coarse thread design significantly reduces installation time while maintaining secure fastening in materials ranging from metal assemblies to durable plastics. The No. 2 Phillips drive provides reliable torque transfer without stripping, making them ideal for production line environments where speed and consistency matter. With fully threaded construction and Class 2A thread fit, these screws maintain precise tolerances for repeated disassembly and reassembly cycles in maintenance applications, equipment manufacturing, and electrical enclosures where vibration resistance is critical.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerance for consistent performance. These 6-32 UNC coarse thread screws feature precise dimensional control with 1 3/4" length and 0.138" thread diameter. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets. The inch system measurement guarantees compatibility with North American industrial standards and replacement part requirements.
