Professional Applications & Engineering Value
This 3/8"-16 UNC hex head screw is engineered to address common industrial challenges such as vibration loosening and material fatigue. Its 18-8 Stainless Steel composition provides excellent resistance to rust and oxidation, making it suitable for marine, chemical processing, and construction applications. The coarse thread design ensures quick assembly and reliable holding power in wood, metal, and composite materials. With a 12" length and partially threaded shank, it offers superior clamp load distribution, preventing joint failure in heavy machinery, structural frameworks, and transportation equipment. The external hex drive facilitates high-torque installation, reducing assembly time and improving productivity on the production line.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit tolerances for consistent engagement and meets ASME B18.2.1 dimensional standards. It is manufactured in the inch system with a thread size of 3/8"-16 UNC and a right-hand thread direction. Compliance declarations include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and safe for various industrial and international markets.
