Wide Flange Hex Nuts made of solid DIN/ISO A2-70 Stainless Steel, corrosion-resistant steel, also known as ASTM-304.A2 / ASTM-304 (18-8) Stainless with 18% Chromium & 8% Nickel content.
Due to their metallurgical properties, stainless steel wide flange nuts are an excellent choice to use in an abrasive environment, such as Hybrid Battery module terminals.
Also, the wide flange surface is designed to distribute the pressure more evenly, resulting in a larger area of contact, which results in improved conductivity (Please see the image with FEA analysis of a pressure profile at 48 lb-in torque as compared to typical DIN 6923 flange nut).
