Professional Applications & Engineering Value
This brass Phillips pan head machine screw addresses critical needs in electrical, marine, and plumbing systems where corrosion resistance is paramount. The 1/4"-20 UNC coarse thread with Class 2A fit provides reliable fastening in soft materials and high-vibration environments, reducing loosening over time. Its rounded pan head profile and No. 3 Phillips drive offer flush mounting and efficient torque transfer, speeding up assembly in tight spaces. The combination of 50,000 psi tensile strength and Rockwell B40 hardness ensures the screw maintains integrity under stress, making it suitable for machinery, instrumentation, and industrial brass screw applications requiring consistent performance and regulatory adherence.
Specification Summary & Compliance
This screw maintains precise Class 2A thread fit per UNC standards, ensuring consistent engagement and interchangeability. Manufacturing follows ASME B18.6.3 specifications for dimensional accuracy, including 0.492" head diameter and 3/8" length. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free of restricted hazardous substances for safe use in global markets.
