Professional Applications & Engineering Value
These 1/4-20 UNC brass slotted rounded head screws deliver exceptional performance in demanding industrial environments where corrosion resistance and reliability are paramount. The brass material inherently resists oxidation and galvanic corrosion, making these fully threaded screws ideal for electrical components, marine hardware, and plumbing systems. The coarse thread design ensures rapid installation and maintains holding power in softer materials, while the Class 2A thread fit provides consistent engagement without binding. The rounded head configuration eliminates sharp edges, reducing injury risk and preventing damage to connected surfaces. These industrial fasteners are engineered to withstand vibration and thermal cycling while maintaining 50,000 psi tensile strength throughout their service life.
Specification Summary & Compliance
These rounded head screws feature precise 1/4-20 UNC coarse threads with Class 2A thread fit per ASME standards, ensuring dimensional accuracy and interchangeability. The 1½" fully threaded length provides consistent engagement depth. Manufacturing complies with ASME B18.6.3 specifications for slotted head machine screws. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming restriction of hazardous substances for global industrial applications.
