Butterfly Bolt Nut Title:

High Strength M4 M8 M12 Stainless Steel Wing Nuts butterfly nuts and bolt plaining butterfly nut for rod


Wing nut stainless Introduction:


Material specifications and classification:

A4 stainless steel (corresponding to SUS316, marine grade): It has superior corrosion resistance, especially able to resist the erosion of strong corrosive media such as seawater and acid-base solutions, and is suitable for harsh corrosive environments such as marine engineering, chemical engineering, and pharmaceuticals;

Other materials: Some scenes will use AISI 303 stainless steel, which has good machining performance and is suitable for customized products with high precision requirements;

Thread specifications: The mainstream is metric M3-M10 or as per your requirements

Total length (L): 22mm-32mm or as per your requirements;

Height (H): 10mm, 12mm, 14mm or as per your requirements

Surface treatment: Most of them use the natural color of stainless steel and are divided into two types of finishes: matte sandblasting (MT) and polishing (PL); The natural color can meet the corrosion resistance requirements;
