Professional Applications & Engineering Value
This flanged thumb nut is engineered to address common industrial challenges such as corrosion, vibration loosening, and the need for rapid assembly without tools. The 18-8 stainless steel material offers excellent resistance to rust and chemical exposure, making it suitable for outdoor, marine, or chemical processing equipment. The knurled round head ensures a firm grip even with oily hands or gloves, enhancing safety and efficiency in maintenance tasks. Its fully threaded design with UNF fine threading provides superior holding power in high-vibration environments like machinery, automotive assemblies, and electronic enclosures. The flange acts as a built-in washer, reducing the risk of damage to soft surfaces and improving load distribution, which is critical in repeated adjustment scenarios.
Specification Summary & Compliance
This thumb nut features a 7/16"-20 UNF thread with Class 2B fit for precise dimensional accuracy and smooth assembly. It complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) standards, ensuring environmental safety and regulatory adherence. Key dimensions include a collar diameter of 11/16", collar height of 5/16", and overall height of 17/32", manufactured to consistent industrial specifications for reliable performance.
