These grades help in choosing the Grades of Bolts - Bolt Grade Marking Chart, p2 Grades of Bolts - Bolt Grade Marking Chart, p3 Tensile Strength: The resistance of a material to breaking under tension Yield Strength: The stress at Metric steel bolts, screws and studs - proof and tensile strength. Learn the essentials of bolt and nut grades, including SAE, ISO, and ASTM standards. For bolts, you can find the SAE J429 grade displayed in radial lines on the head, which indicate the Bolt grades are a standardized way of categorizing bolts based on their mechanical properties, such as tensile strength, yield strength, and hardness. Selecting the appropriate bolt strength is a crucial decision in many engineering, construction, and manufacturing projects. Bolt Grade Markings & Strength American Bolts Metric Bolts Tensile Strength: The maximum load in tension (pulling apart) which a material can withstand before breaking or fracturing. Hardware Menu Hex Bolt Identification, Markings and Strength Chart Table Guide Hex Bolt Identification, Markings and Strength Chart. Bolts are responsible for holding together everything from buildings to The metric bolt grades are designated by a symbol of 2 numbers, separated by a decimal. (the ratio of the Proof (or Yield ) stress and the Tensile strength expressed as a percentage = 100. The strength of a bolt is represented by its grade, which indicates its tensile strength (the maximum stress a bolt can support when it is under tensile Bolt Grades - Head Marking and Rod End Reference Guide Bolts and Rod Ends Specification Data The first number is the tensile strength of the bolt material (N 2 )/100.
