Professional Applications & Engineering Value
This 5/16"-18 UNC brass slotted rounded head screw delivers outstanding performance in demanding industrial settings where corrosion resistance and mechanical strength are critical. The brass material inherently resists oxidation and galvanic corrosion, making it perfect for electrical components, plumbing systems, and marine equipment. The coarse UNC threading combined with Class 2A thread fit ensures rapid installation and secure fastening in soft materials or where vibration resistance is needed. Its fully threaded body distributes stress evenly, reducing the risk of stripping or failure. The rounded head with slotted drive provides a low-profile, safe finish that minimizes protrusion hazards in assembled machinery, while meeting ASME B18.6.3 specifications for consistent dimensional accuracy and reliability.
Specification Summary & Compliance
This screw features precise Class 2A thread fit per UNC standards, with a diameter of 0.313" and coarse thread spacing for optimal engagement. It is manufactured in compliance with ASME B18.6.3 for dimensional and mechanical requirements, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and safe for various industrial and international applications.
