Alloy 20 Bolts are made up of a nickel chromium alloy that has 32.5% nickel, 19% chromium, carbon, copper, molybdenum, manganese, silicon, columbium and iron in the composition. Suraj Metal Corporation is a leading manufacturer and supplier of the Alloy 20 Hex Bolt and other types of fasteners in the alloy 20 material. The material is also known as carpenter 20 for its usage in wooden applications.
The Alloy 20 Screws are strong with 80ksi minimum tensile strength and 35ksi minimum yield strength. The material also has high hardness with 217HBW. The Alloy 20 Stainless Steel Stud Bolts are used to connect two components together by use of the stud protrusion. The fasteners come in ¼ inches to 1 ½ inches in size. The Alloy 20 Hex Nuts are one of the most used forms of the nuts as they have good grip for loosening and tightening. There are threaded rods as well. The Alloy 20 Threaded Rod is useful in fitting two parts together without the use of a screw head or bolt. The threaded rods might have threads on only one end or on both ends. As a supplier of the fasteners we supply all types such as the Alloy 20 N08020 Washer. The washers are important to fill in the gaps, absorbing stress and vibrations in heavy load systems. Please feel free to contact us for more information on the different types of fasteners such as the Carpenter Alloy 20cb3 Socket Head Cap Screw and their prices.
