ASTM A490 Bolt Torque Chart The ASTM A490 is a specification for the bolts set by the ASTM International, a voluntary standards development organizations that sets technical standards for materials. ASTM A490 covers heavy hex structural bolts from 1/2 inch diameter through 1-1/2 inches diameter and are made of alloy steel.
ASTM A490 Specification - Southern Fasteners and Supply, Scope This specification covers quenched and tempered, alloy steel, heavy hex structural bolts from 1/2 1-1/2 diameter with a min. 150 ksi tensile.These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts. This spec is similar to but stronger than ASTM A325 being that A490 is made from alloy steel rather than a
This specification covers two types of bolting grades quenched and tempered, manufactured from high strength alloy steel. ASTM A490 Bolts are intended for used in structural connections similar to ASTM A325/A325M but being produced from alloy steel instead of medium carbon steel
ASTM F3125-A490 - Precision BoltsASTM A490 (F3125) Structural bolts, steel, heat treated, 150 ksi minimum tensile strength. The ASTM A490 specification cover quenched and tempered, alloy steel, heavy hex structural bolts from 1/2 diameter through 1-1/2 diameter with a minimum 150 ksi tensile.

ASTM A490 and ASTM A490M are ASTM International standards for heavy hex structural bolts made from alloy steel. The imperial standard is officially titled Standard Specification for Structural Bolts, Alloy Steel, Heat Treated, 150 ksi Minimum Tensile Strength, while the metric standard (M) is titled Standard Specification for High-Strength Steel Bolts, Classes 10.9 and 10.9.3, for Structural
Structural Bolts FastenalThis specification contains 4 inch series bolting grades:A325, F1852, A490, and F2280. These will be addressed in this article. When looking at the mechanical requirements of bolts it appears that a grade A325 and SAE J429 Grade 5 are identical as do the grade A490 and the SAE J429 Grade 8.
What Are the Different Grades of Bolts? HunkerA grade 2 bolt made of low-carbon steel has a tensile strength of 64,000 pounds per square inch or less. Tensile strength is the amount of pull the bolt can withstand before breaking. A bolt head with three raised dashes in a radial pattern marks an SAE grade 5 bolt of tempered medium carbon steel with a tensile strength of at least 105,000
Equivalent Grades:Aluminium and aluminium alloys Equivalent Grades:Copper and copper alloys Equivalent Grades:Magnesium and magnesium alloys Equivalent Grades:Zinc and zinc alloys Equivalent GradesStructural Bolts - ASTM A325 & ASTM A490 AALL The chemical and mechanical specifications included in ASME B18.2.6 are governed by the American Society for Testing and Materials (ASTM) designated by ASTM F3125. In 2016, ASTM F3125 replaced ASTM A325 and ASTM A490 which are now grades under the new ASTM F3125 Standard. ASTM A325 and ASTM A490 are still widely used terms throughout the industry.
