Professional Applications & Engineering Value
This 1/4"-20 UNC brass rounded head slotted screw delivers exceptional engineering value through its corrosion-resistant brass material and fully threaded coarse UNC design. The combination addresses critical industrial challenges where fastener failure can compromise system integrity. The rounded head profile minimizes protrusion while distributing stress evenly, making it ideal for applications requiring flush mounting without sharp edges. With its Class 2A thread fit and slotted drive style, installation becomes more efficient in electrical enclosures, marine hardware, plumbing systems, and precision instrumentation where reliable fastening performance and environmental resistance are paramount. The 50,000 psi tensile strength ensures secure connections in vibration-prone environments while maintaining compliance with industry standards.
Specification Summary & Compliance
This fastener maintains Class 2A thread fit tolerance with UNC coarse threads (1/4"-20) in right-hand direction, manufactured to ASME B18.6.3 specifications. The screw features full threading along its 1 1/4" length with standard rounded head profile (0.472" diameter, 0.175" height). Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for restricted substance-sensitive applications.
