Stainless Steel 420 Fasteners are made up of a martensitic stainless steel with 12% chromium, sulfur, phosphorus, silicon, manganese and carbon in the composition. The material has 690MPa minimum tensile strength and 414MPa minimum yield strength. There are different types of fasteners such as SS UNS S42000 Hex Head Bolts, studs, threaded rods, screws, washers and nuts. The different types of fasteners come with different dimensions according to the different standards. The SS 420 Bolt has higher melting point of 1495 degrees Celsius and 15% elongation rate.

Grade 420 Threaded rod
This allows the fasteners to be used in high temperature applications. The specification for the fasteners are the ASTM A193 and A194. These specifications cover fasteners for high temperature and high pressure applications. The 420 Stainless Steel Bolt can come under the ASTM, DIN and all other international standards. The size of the fasteners range from M02 to M33 and the length of the fasteners range from 3mm to 200mm. There are different screw types and head types to the fasteners. The threads vary as fine threads and coarse threads where the head differs as ASTM A193 420 Stainless Steel Hex Bolt, square head and other types. The hex head bolts are used in heavy torque applications as they can withstand high stress. For load bearing applications, the Stainless Steel 420 Eye Nuts are used. The nuts can differ in types and shapes such as the hex nuts, lag nuts and cap nuts as well. The applications of these fasteners can be seen in oil and gas, automobile, sea water, water line, heat exchanger and other high temperature high pressure applications as well.
