• Optimized flange dimensions (5/8" collar, 3/4" head) providing stable mounting without additional components

Professional Applications & Engineering Value

This flanged thumb nut solves critical assembly challenges where tool access is limited and corrosion resistance is paramount. The 18-8 Stainless Steel construction provides excellent durability against moisture, chemicals, and outdoor exposure, while the knurled round head delivers positive grip even with oily hands or gloves. The integrated flange design eliminates the need for separate washers in panel mounting, machinery guards, and electrical enclosures, reducing part count and installation time. With 3/8"-16 UNC coarse threading and Class 2B thread fit, it maintains secure fastening in high-vibration applications across automotive, marine, and industrial equipment where frequent adjustments are required.

Specification Summary & Compliance

Manufactured to precise Class 2B thread tolerances with UNC coarse thread standard (3/8"-16) and right-hand threading direction. The component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental safety standards. Physical dimensions include 5/8" collar diameter, 3/4" head diameter, and 15/32" total height with fully threaded internal construction for consistent performance across the entire fastener length.
