Professional Applications & Engineering Value
This 3/8"-16 UNC Rounded Head Flanged Screw is engineered to address common industrial challenges such as vibration-induced loosening and material degradation. Constructed from 18-8 Stainless Steel with a passivated finish, it provides excellent resistance to rust and chemical exposure, making it suitable for outdoor, marine, and chemical processing equipment. The Class 3A thread fit and coarse UNC threading ensure tight tolerances and rapid installation, reducing assembly time while maintaining joint integrity. The flanged design distributes clamping force evenly, preventing surface damage and improving stability in machinery, automotive, and structural frameworks. Its partial threading allows for precise grip length control, ideal for applications requiring specific unthreaded shank sections.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Key dimensions include a 3/8"-16 thread size, 1 1/2" length, and 0.813" flange diameter. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
