One of the main manufacturer and suppliers of SS 304 Hex Bolt is the Stainless Bolts Industries. These bolts are famous for their property and reliability in corrosion as well as their strength and dependability in engineering, construction, and other branches of industry. They are made from finest 304 stainless steel grades which can withstand very harsh environments such as chemicals, moisture, and extreme high temperature. The hex head shape allows for simple and safe assembly as tightening with standard tools ensures secure fastening. In both imperial (inch) and metric (mm) measurements, we offer a wide range of SS 304 Hex Bolts with various thread options including full thread and half thread. Whether for heavy machinery, steel constructions, or marine applications, our SS 304 Hex Bolts provide outstanding value and performance.
Due to its great strength, resistance to corrosion, and longevity SS 304 Hex bolt are a key element in many commercial and industrial applications. In the construction, automotive, maritime, chemical processing, food manufacturing and other industries you will see heavy use of these bolt nuts. What we call premium stainless steel 304 at times is also known as A2 stainless steel. It is the excellent material properties of these that make them the best for use in the fastening of bolts and fasteners in areas which are subject to heat, moisture, and chemicals.
