Professional Applications & Engineering Value
This 18-8 stainless steel thumb nut delivers exceptional performance in industrial settings where frequent adjustments and corrosion resistance are critical. The flanged design acts as a built-in washer, distributing clamp load over a wider area to prevent damage to soft materials and maintain joint integrity under vibration. Its fully threaded UNF fine thread (5/16"-24) and Class 2B fit provide precise, repeatable fastening with minimal risk of cross-threading, making it ideal for machinery, electronic enclosures, and automotive applications requiring hand-operated components. The knurled round head ensures a non-slip grip even with oily hands, enhancing operator safety and efficiency in maintenance-heavy environments.
Specification Summary & Compliance
Manufactured to inch system standards with Class 2B thread fit for consistent accuracy and interchangeability. Thread specifications adhere to UNF fine thread (5/16"-24, right-hand) with full threading for optimal engagement. Compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, ensuring environmental safety and regulatory adherence. Dimensions include collar diameter 17/32", collar height 7/32", head diameter 5/8", and overall height 13/32" for precise integration into assemblies.
