A194/A194M Specification for Carbon and Alloy Steel Nuts for Bolts for High Pressure or High Temperature Service, or Both A325 Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile StrengthASTM A490 Fasteners ASTM A490 Scope. The ASTM A490 specification covers quenched and tempered, alloy steel, heavy hex structural bolts from 1/2" diameter through 1-1/2" diameter with a minimum 150 ksi tensile. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts. Manufactured and certified to A325 and A490 Formed on precision high speed cold-formers Designed for steel-to-steel structural connections Full Traceability Holo-Krome USA: 1.800.879.6205 europe: +31 (0) 78 652 4145 www.holo-krome.com A325 & A490 STRUCTURAL BOLTS CELEBRATING 90 YEARS OF QUALITY HOLO-KROME has been at theASTM A490 bolts are heavy hex bolts made of alloy steel with a flat bearing surface, washer faced, and chamfered point. They are used in structural steel joints in heavy construction applications that require greater yield and tensile strengths than those of an A325 bolt are required.
Original video found at https://www.youtube.com/watch?v=OpKwdzGLbjc.ASTM F3125 covers high strength structural bolts including Grades A325 and A490. These bolts are designed for steel-to-steel structural connections and include heavy hex bolts and tension control bolts. birmingham fastener houses the nation’s largest inventory of structural bolting components, both domestic and imported. Custom sizing is.ASTM A490 Scope – This specification covers quenched and tempered, alloy steel, heavy hex structural bolts from 1/2" to 1-1/2" diameter with a minimum 150 ksi tensile. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts. ThisA490 is a ASTM International specification for heavy hex structural bolts. A490 covers two types of quenched and tempered, alloy steel heavy hex structural bolts having a tensile strength of 150 to 173 ksi. These bolts are intended for structural connections and are furnished in sizes 1/2&Tension Control Bolts, TC Bolts or Twist Off Bolts are now the most popular choice in high-strength structural bolting and formally recognized by the aisc (american institute of Steel Construction) and the RCSC (Research Council on Structural Connections) as an approved installation method.
