These products find their applications in machinery, automotive, electronic components, electrical, construction, railway, and various industries. these are available in different bolt lengths and sizes. It is made up of Stainless steel (SS304) material which offers high tensile strength and excellent corrosion protection. Stainless steel (SS304) has a higher Mild content and with a matte finish, it gives the steel a lower melting point, more malleability and durability, and better heat distribution. These screws have good chemical resistance and may be mildly magnetic. Length is measured from under the head. Metric screws are also known as A2 stainless steel screws.
