Professional Applications & Engineering Value
These 4-40 UNC zinc-plated steel rounded head Phillips screws are engineered to address common industrial fastening challenges, such as corrosion and mechanical stress. The zinc plating provides a protective barrier against moisture and chemicals, extending service life in applications like machinery assembly, electronics enclosures, and automotive components. With a coarse thread and Class 2A fit, they offer superior engagement in softer materials, reducing the likelihood of stripping. The pan head style and fully threaded design ensure even load distribution and maximum retention, making them ideal for industrial uses where vibration resistance and reliability are critical. By meeting ASME B18.6.3 standards, these screws deliver consistent quality and performance, minimizing downtime and maintenance costs.
Specification Summary & Compliance
This product features precise Class 2A thread fit with UNC coarse threads and a length of 1", manufactured to ASME B18.6.3 specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial applications.
