The B16 Set screws and other fasteners that are greater than M100 and up to M180 in diameter have 690MPa minimum tensile strength and 585MPa minimum yield strength. The SS A193 B16 Flange Bolts are used with inbuilt flanges. These flanges help the nuts to stay in place while fastening and after connection. The material is chromium, molybdenum, and vanadium alloy steel. Therefore the ASTM A193 Gr B16 Socket head cap screw is much corrosion resistant to general corrosive applications. There are different types of fasteners such as the SA-193-B16 lock Nuts which are used mostly in automobile wheels to make sure that the nuts don’t loosen due to high vibration. The ASTM A193 Grade B16 Bolts can be heat treated. The usual heat treatment is the quenched and tempered method. The A193 B16 Material needs to be heated to 860 degrees Celsius minimum to get the desired heat treated hardness. The B16 Nut Bolt is used in some of the high tensile and high stress applications such as power plants, boilers, railway tracks and others. The B16 Head Bolts are one of the special types. Each of the different types of bolts in this specification are used under high temperature, high pressure conditions.
ASME SA 193 B16 Hex Nuts are made up of carbon, manganese, phosphorus, sulfur, chromium, molybdenum, vanadium and aluminum in the composition. One of the most used types is the SA 193 B16 Hex Bolts that are used for high strength and connection. The diameters of the ASTM A193 B16 Nuts range up to M100 for fasteners with 760MPa minimum tensile strength and 655MPa minimum yield strength.
