Professional Applications & Engineering Value
This brass slotted round head screw with 1/4"-20 UNC coarse thread is engineered to solve critical fastening challenges in industrial settings. The brass material provides inherent corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or outdoor elements where steel fasteners would deteriorate. The rounded head profile and slotted drive facilitate quick installation in tight spaces while maintaining a low profile. With 50,000 psi tensile strength and Rockwell B40 hardness, it withstands vibration and mechanical stress in machinery, electrical enclosures, and plumbing systems. The fully threaded design ensures maximum engagement in tapped holes or nuts, preventing loosening under dynamic loads. These screws are particularly valuable in marine, HVAC, and electrical industries where corrosion-resistant fasteners must maintain integrity while complying with strict industry standards.
Specification Summary & Compliance
This screw features precise 1/4"-20 UNC coarse threads with Class 2A thread fit for consistent dimensional accuracy. Manufacturing adheres to ASME B18.6.3 specifications for mechanical and dimensional requirements. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets current environmental and safety standards for hazardous substance restrictions.
