Professional Applications & Engineering Value
This 1/4"-20 UNC brass rounded head screw delivers critical performance advantages in industrial settings where corrosion resistance and electrical conductivity are paramount. The Class 3A thread fit provides precise, reliable fastening in components requiring repeated assembly/disassembly, while the coarse UNC threading ensures quick installation and superior vibration resistance. The combination of 50,000 psi tensile strength and Rockwell B55 hardness makes these hex drive screws ideal for electrical enclosures, marine equipment, and plumbing systems where brass's non-sparking properties add safety benefits. The fully threaded design maximizes surface contact for enhanced load distribution in thin materials.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit per UNC specifications. Features 1/4"-20 coarse threading, 3/16" length, and 5/32" hex drive. Complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance.
