Bolt and nut picture gallery

One of our primary objectives to illustrate the picture of bolts and nuts has been not only to introduce to you the shape, type and the thread of them but to help you differentiate the material and coating based on the color.

• Non-Galvanized alloy steel or carbon steel bolts and nuts are dark and are covered with oil
• Cold Galvanized bolts and nuts have a silver or goldish color
• Hot-deep galvanized and dacromet bolts and nuts are blurry silver
• Stainless steel bolts and nuts have a yeloowish silver surface.
