• Environmentally responsible manufacturing with full RoHS 3 and REACH compliance

Professional Applications & Engineering Value

This 6-32 UNC thumb screw in 18-8 stainless steel delivers critical performance where frequent access and corrosion resistance are paramount. The knurled head provides positive grip even with gloved hands, speeding up maintenance on captive panel assemblies in electronics, telecommunications, and industrial control systems. Its partially threaded shank ensures the screw remains securely captured in the panel while allowing precise clamping force. The coarse thread design resists cross-threading during quick installations, making it an efficient solution for high-vibration environments where reliability cannot be compromised.

Specification Summary & Compliance

This thumb screw features precise Class 2A thread fit with 6-32 UNC coarse threading and a length of 7/8". Manufactured to ASTM A581 specifications for consistent material properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets.
