Professional Applications & Engineering Value
This 10-32 UNF thumb screw in 18-8 stainless steel is engineered to address common industrial challenges such as frequent adjustments and exposure to corrosive elements. The knurled round head provides a non-slip surface, enabling quick, tool-free installation and removal—ideal for maintenance panels, electronic enclosures, and machinery covers. Its low-profile design minimizes protrusion, reducing the risk of snagging in compact assemblies. The fine UNF threads and Class 2A fit ensure tight, secure fastening that resists loosening under vibration, while the partial threading offers flexibility in depth adjustment. With excellent corrosion resistance, this screw is suited for outdoor equipment, marine applications, and chemical processing facilities, delivering reliability without the need for specialized tools.
Specification Summary & Compliance
This thumb screw features a 10-32 UNF thread with Class 2A fit for precise dimensional accuracy, a 3/4" knurled head diameter, and a low-profile round head design. It is manufactured from 18-8 stainless steel with a tensile strength of 80,000 psi and Rockwell B83 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use.
