Professional Applications & Engineering Value
This 3/8"-16 UNC brass hex head screw delivers exceptional value in industrial settings where corrosion resistance and mechanical integrity are critical. The brass material inherently resists rust and galvanic corrosion, making it perfect for marine, plumbing, and electrical applications. With its coarse thread design and Class 2A thread fit, it provides rapid assembly in soft materials like wood and plastic while maintaining secure fastening. The external hex drive allows for high-torque installation, and the partial threading offers unthreaded shank strength where needed. Engineers specify this screw for heavy-duty assemblies requiring 50,000 psi tensile strength and compliance with ASME B18.2.1 standards, ensuring long-term reliability in vibration-prone environments.
Specification Summary & Compliance
This inch-system fastener features precise 3/8"-16 UNC coarse threads with Class 2A thread fit for consistent dimensional accuracy. It meets ASME B18.2.1 manufacturing specifications, ensuring interchangeability and performance. The screw is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to environmental and safety regulations for hazardous substances. With a Rockwell B55 hardness and 50,000 psi tensile strength, it is manufactured to deliver reliable mechanical performance in industrial applications.
