GB/T 6177.1 Hexagon Flange Nuts – Style 2 | High Strength | Stainless & Carbon Steel | OEM Available

Description

The GB/T 6177.1 Hexagon Nut with Flange (Style 2) is a high-performance fastening solution designed to provide a wider bearing surface through its built-in flange, which helps evenly distribute pressure and reduce the chance of loosening under vibration. Commonly used in machinery, automotive, and structural assembly, this style offers a more robust build than standard flange nuts.

Available in carbon steel and stainless steel, and offered in multiple grades (4.8, 8.8, 10.9, 12.9), these nuts are compliant with major global standards (GB, DIN, ISO, ANSI/ASTM, BS, JIS). Surface finish options such as zinc plating, hot-dip galvanizing, black oxide, and more ensure corrosion resistance tailored to your needs.
