Professional Applications & Engineering Value
This 6-32 UNC Thumb Screw is engineered to solve critical challenges in industrial maintenance, electronics assembly, and machinery access panels. The 18-8 Stainless Steel material offers superior resistance to rust and oxidation, making it ideal for applications exposed to moisture or chemicals. The coarse UNC thread and Class 2A thread fit ensure rapid installation and vibration resistance, reducing assembly time and maintenance frequency. The knurled head provides a secure, non-slip grip, even with gloved hands, eliminating the need for tools in hard-to-reach areas. This combination of a narrow profile round head and partially threaded design delivers precise clamping force and prevents over-tightening, protecting sensitive components in industrial thumb screw applications.
Specification Summary & Compliance
This thumb screw features a 6-32 UNC thread with a Class 2A thread fit for precise dimensional accuracy and reliable performance. Key dimensions include a 0.138" thread diameter, coarse thread spacing, and a 3/4" overall length. The product is manufactured from 18-8 Stainless Steel and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
