Made of stainless steel or carbon steel, these bolts are polished to a mirror finish and provide excellent corrosion resistance.The unique head styling not only gives fantastic good looks but also provides a functional element as the washer base spreads the load.These are also machined with rolled threads to give extra strength and a smoother finish.Flange bolts virtually eliminate the need for washers because the area under the bolt head is wider and creates a larger area for even distribution of pressure. We also supply hex flange nuts that work in tandem with our hex flange bolts. We have different grades of hex flange bolts, hex flange nuts, and hex flange screws to fit a wide range of applications. Stainless steel is widely used in the fastener industry,which not only looks great but has other benefits too..
