Professional Applications & Engineering Value
These 3/8"-16 UNC Rounded Head Phillips Screws are engineered to address common challenges in industrial assembly, such as corrosion-induced failure and joint loosening under dynamic loads. The 18-8 Stainless Steel material, combined with a passivated finish, provides excellent resistance to oxidation and chemical exposure, making them suitable for outdoor equipment, food processing machinery, and marine applications. The coarse UNC thread and Class 2A thread fit facilitate quick installation and maintain clamp force in materials prone to stripping. With a fully threaded design and high tensile strength, they ensure uniform stress distribution and long-term reliability in structural frameworks, conveyor systems, and heavy-duty enclosures, reducing maintenance downtime and replacement costs.
Specification Summary & Compliance
This screw features a 3/8"-16 UNC thread with Class 2A dimensional tolerance for precise fit. It is manufactured in compliance with ASME B18.6.3 specifications, ensuring consistent quality and performance. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, confirming it is free of hazardous substances and safe for various industrial and international markets.
