Professional Applications & Engineering Value
This 6-32 UNC thumb screw is engineered to solve common industrial challenges where tool-less access and frequent adjustments are required. The black-oxide steel construction offers enhanced resistance to rust and wear, making it ideal for industrial applications in electronics, machinery panels, and assembly jigs that are subject to handling and environmental exposure. The coarse thread spacing and fully threaded design ensure quick and deep penetration into materials, reducing the risk of cross-threading and providing a robust, reliable fastening solution. The knurled head with a raised profile delivers maximum torque application by hand, streamlining maintenance and reducing assembly time without the need for specialized tools.
Specification Summary & Compliance
This thumb screw adheres to the UNC thread standard with a Class 2A thread fit, ensuring precise dimensional accuracy and reliable performance. It is manufactured to meet RoHS 3 (2015/863/EU) compliance with exemption 6(a)-I and is REACH (EC 1907/2006) compliant, confirming its suitability for use in environments with strict regulatory requirements for hazardous substances.
