In general, since the minimum strength requirement of a Grade 2 is greater than that of an A307A, a Grade 2 can be successfully utilized in applications where an A307A is specified, as approved by the “Engineer of Record”. The SAE marking standard starts with grade 2, indicated by a bolt head with no markings whatsoever. A 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. 14.09.2020 · Bolt Depot - Standard U.S. Hex Bolt Sizes and Thread Pitches.pdf. Bolt Grade Markings and Strength Chart.

As the vast majority of U-bolts are subject to a tensile service load, tensile strength is the primary determining factor of grade, material and diameter selection. 3. The general hardness of a U-bolt is usually not a consideration in the service life as there is often no wear involved. Replace a graded fastener with same or higher grade (don't replace a Grade 8 fastener with a Grade 5 or 2). If in doubt, ask a professional for assistance. The chart below summarizes some of the more common grades and classes available here at Fastener Mart . Except for the very lowest grades, metric nuts and bolts all carry identification markings which indicate their strength.

There are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9. Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher the number means the stronger the bolt.
