Metric Bolt Classes Keywords: Metric Bolt Grades; Metric Bolt Classes; Bolt Grade Markings and strength chart; Metric bolt tensile strength; Metric Bolt Identification; Bolt class 4. Torq Bolt is a leading manufacturer and exporter of ASTM A574 Bolts in India. 8) Tensile: 1220MPa Grade ASTM-A574 120,000 psi 150,000 psi 170,000 psi 120,350 psi 150,800 psi 176,900 psi Bolt Torque Specs in Foot Pounds or (Inch Pounds) Tensile: 830MPa Tensile: 1040MPa Size/Thread Bolt Torque Specs in Foot Pounds or (Inch Pounds) Size/Thread Grade 5 Grade 8 Grade ASTM-A574 Class Tensile Torque Reference. ASTM F3125 Grade F2280 (A490 TC) Structural bolts, steel, heat treated, 120 ksi minimum tensile strength. 2 - proof and tensile strength. ASTM Reference Chart Grade Pipe Tubing Weld Forging Plate Specs. Test loads should be a minimum of eighty (80) percent of yield strength or proof load and held for a minimum of 168 hours. ASTM A193 Grade B8M Specification. view b7 alloy steel threaded rod, b7 alloy steel bolts Price in Mumbai, India. Alloy Steel High-Tensile Class 8. ASTM A193 Grade B7 bolts and threaded studs are manufactured from a chromium-molybdenum steel and are quenched and tempered (heat treated) to develop the desired mechanical properties (strength). A490 STRUCTURAL BOLTS. Several ASTM specifications require a hex head that is larger than a standard (finished) hex head. Read more.

The first digit relates to the ultimate strength of the material, whilst the second is the ratio of yield stress to ultimate strength. Bolts secure material by applying pressure from the head of the bolt. astm a193 Standard Specification for Alloy Steel and Stainless Steel for High Temperature or High Pressure Service and Other Special Applications. These anchor bolts are available in Grade 36, Grade 55, and Grade 105 - the number after the grade designates the fastener's minimum yield strength (measured in ksi). ASTM F3125 Grade F1852 (A325 TC) Structural bolts, steel, heat treated, 120 ksi minimum tensile strength. F1554 Grade 36 formerly known as ASTM A307 grade C, is the most commonly requested material for anchor bolts. " These assemblies are capable of developing a minimum. ASTM A563 Nuts Specifications. The reason that A194 grade 2H nuts are used more often with A193 grade B7 bolts is simply cost. 8; Bolt class 8. Our metric grade A-2 bolts, also known as 18/8 bolts, meet ASTM 304 standards. Where ASTM A449 becomes a potential alternative for A325 is when the strength of an A325 is desired, but the actual part is an anchor bolt or a configuration other than a heavy hex bolt for steel to steel connections. ASTM A307 covers low carbon steel bolts and currently consists of Grades A and B. ASTM A193 specification for alloy-steel and stainless steel fasteners for high tensile or high temperature applications. Notes - A490 bolts shall not be coated via hot-dip zinc coating, mechanical deposition, or electroplating with zinc due to the potential for hydrogen embrittlement. Mostly ASTM A193 Grade B7 bolts are selected along with ASTM A194 Grade 2H nuts. There are three grades A, B, and C* which denote tensile strength, configuration, and application. In addition to many different sizes and grades of ASTM A193 Grade B8 Stud Bolts, we also carry one of the largest inventories of ASTM A194 Grade 8 & 8M stainless heavy hex nuts in North America. Hex head bolts M5 and larger must have the property class marked on the head of the bolt, either in raised or depressed lettering.
