Professional Applications & Engineering Value

This 18-8 stainless steel flanged thumb nut is engineered to address common challenges in industrial settings where tool-free, rapid assembly is critical. The deep knurling on the round head provides exceptional finger grip, reducing slippage and enabling secure tightening in confined spaces or high-vibration environments. Made from corrosion-resistant 18-8 stainless steel, it excels in applications exposed to moisture, chemicals, or outdoor conditions, such as machinery panels, electronic enclosures, and automotive components. The flanged design distributes clamping force evenly, minimizing surface damage and enhancing joint integrity. With UNC coarse threading and a right-hand thread direction, it ensures quick engagement and reliable performance, making it a go-to solution for maintenance, prototyping, and production lines requiring efficient, hand-operated fastening.

Specification Summary & Compliance

This thumb nut adheres to UNC coarse thread standards with a size of 1/4"-20 and a Class 2B thread fit for consistent dimensional accuracy. It features a partially threaded design with a thread depth of 5/16" and is manufactured from 18-8 stainless steel for durability. The product is compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring it meets stringent environmental and safety requirements for industrial use.
