Professional Applications & Engineering Value
These brass pan head Phillips screws with 1/4-20 UNC coarse threading deliver exceptional value in applications where corrosion resistance and electrical conductivity are critical. The rounded head profile provides a finished appearance while the fully threaded design ensures maximum engagement in materials ranging from plastics to softer metals. Engineers specify these fasteners for electrical enclosures, marine equipment, and plumbing systems where brass material prevents galvanic corrosion and maintains performance in moist environments. The Class 2A thread fit and coarse thread spacing facilitate quick assembly while maintaining vibration resistance, making them ideal for production lines requiring both speed and reliability.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with Class 2A thread fit tolerance per UNC standards. These 1/4-20 UNC screws comply with ASME B18.6.3 manufacturing specifications and meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The right-hand thread direction and coarse thread spacing ensure compatibility with standard industrial components and fastening systems.
