Professional Applications & Engineering Value
This brass pan head machine screw is engineered to address common industrial challenges including corrosion, electrical interference, and mechanical stress. The 1/4"-20 UNC coarse thread configuration provides quick assembly and strong holding power in metal, plastic, and wood applications, reducing installation time while maintaining 50,000 psi tensile strength. The brass material offers natural corrosion resistance without requiring additional plating, making it perfect for marine, electrical, and plumbing systems where environmental factors degrade ordinary fasteners. The fully threaded design ensures consistent clamping force across the entire length, preventing loosening from vibration - a critical advantage in machinery, automotive, and HVAC applications.
Specification Summary & Compliance
This screw maintains precise Class 2A thread fit tolerances with UNC coarse threads (1/4"-20) in a right-hand orientation. Manufacturing strictly follows ASME B18.6.3 specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial and commercial applications without hazardous substance restrictions.
