Professional Applications & Engineering Value
These 1/4-20 UNC brass rounded head screws deliver critical performance advantages where corrosion resistance and electrical conductivity are paramount. The coarse UNC thread design ensures rapid installation and superior holding power in soft materials and repeated assembly applications. Engineered with Class 3A thread fit precision, these fasteners eliminate play in high-vibration environments common in electrical enclosures, marine equipment, and plumbing systems. The hex drive configuration provides maximum torque transfer without cam-out issues, while the brass material naturally resists galvanic corrosion when mating with dissimilar metals. These fully threaded screws maintain consistent clamping force across the entire engagement length, making them ideal for industrial fastening applications requiring reliable, maintenance-free performance.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit tolerances and UNC coarse thread specifications. These brass rounded head screws comply with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys and meet REACH (EC 1907/2006) compliance requirements. The fasteners feature standardized 1/4"-20 thread size with right-hand thread direction and are supplied as fully threaded components for consistent performance across industrial applications.
