Professional Applications & Engineering Value
This heavy-duty 3/8"-16 UNC Thumb Screw is engineered to solve common industrial fastening challenges. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it perfect for use in manufacturing, machinery, and outdoor equipment where exposure to moisture is a concern. The knurled head texture offers maximum grip, allowing for high-torque manual tightening and loosening without the need for tools, which speeds up maintenance and adjustments. Its partially threaded and low-profile round head design ensures it fits in tight spaces while the extended tip facilitates easy insertion into threaded holes, reducing the risk of cross-threading. This combination of features delivers a reliable, user-friendly thumb screw solution that enhances operational efficiency in assembly lines, electrical enclosures, and fixture applications.
Specification Summary & Compliance
This thumb screw features a 3/8"-16 UNC thread with a Class 2A fit for standard dimensional accuracy and reliable performance. It is manufactured from 18-8 Stainless Steel and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring it is free of hazardous substances and safe for various industrial uses.
