    Plain Color DIN6921 Stainless Steel Bolts , Hex Flange Bolt With 50mm Length


    Plain Color DIN6921 Stainless Steel Bolts , Hex Flange Bolt With 50mm Length


    1.Product Description


    Stainless steel hexagonal flange bolts, made of stainless steel material, the standard is DIN6921. Flange bolts are made of hexagonal head and flange. They are used to fasten and connect the through hole parts of two bolts. According to the position of flange bolts, the size and requirements of discs are different, and the anti-slip effect of flattened teeth and teeth are also included. The surface color is of color. It can also be divided into white, green, yellow and corrosion resistant Dacromet coatings according to different needs. The company operates fasteners for many years, has rich experience, high quality, and has a professional testing agency, providing relevant testing certificates, and can be customized according to customer needs and drawings.

    3.Application


    The head of hexagonal flange bolt is composed of hexagonal head and flange face. The word ratio of support area to stress area of hexagonal head bolt is larger than that of ordinary hexagonal head bolt. Therefore, this kind of bolt can withstand higher preload and has better anti-loosening performance. Therefore, it is widely used in automobile engines, heavy machinery and other products. Bolts with holes and grooves in the head of hexagonal head can be locked by mechanical method in order to prevent loosening and reliability.


    4.Advantages


    1 Flange connections may have to withstand high tensile, compressive, torsional, and shear strength. Carbon steel flanges are a good choice. The nominal pressure is determined not only according to the highest working pressure, but also according to the highest working temperature and material characteristics, not just the nominal pressure greater than the working pressure.


    2. A flange is a connection between two large diameter pipes, usually two flanges plus a number of fastening bolts. Carbon steel flanges are flanges made of carbon steel. Low-carbon steel has good plasticity and low strength. When a proper amount of carbon is added, it becomes hard and the plasticity is reduced.
