Stainless Steel 304 Flange Nut With Serration M8 (Dia-8mm)

An SS304 serrated flange nut is a corrosion-resistant, high-strength stainless steel fastener with an integrated, serrated washer base. The serrations act as a locking mechanism to prevent loosening from vibration, while the flange distributes pressure to protect surfaces. Often referred to as A2-70, these nuts are ideal for automotive, machinery, and construction applications requiring secure, non-slip fastening.

Key Features and Description
Material: Made from high-quality 304 Stainless Steel (or 18-8 stainless steel), providing excellent resistance to rust, moisture, and corrosion.

Design: Combines a hex nut with a wide, circular base (flange) that has angled teeth (serrations) on the bearing surface.

Locking Function: The serrations grip the mating surface, preventing the nut from rotating or loosening, especially under vibration.

Pressure Distribution: The flange acts as a built-in washer, distributing pressure evenly over a larger area, which reduces the likelihood of damaging the component being fastened.

Specifications: Commonly available in metric (M3-M20) and imperial sizes, often adhering to DIN 6923 standards.

Applications: Widely used in industries requiring high-security, such as automotive, plumbing, solar mounting, construction machinery, and shipbuilding.
