Here, we offer a chart with different grades of bolts and their mechanical properties. And the image in the chart can also help to exhibit the grades of bolts with the identification marks on the bolt’s head as well as the hardness and strength of common grade bolts. Note that bolt heads may also contain the manufacturer’s identification stamp, esp...
Bolt grades refer to the strength and durability of a bolt, which is typically determined by the material it is made of. The grade of bolts is stamped on a bolt head as a marking that indicates the type of material the bolt is made of and its strength rating. For instance, Grade 2 bolts are made of low-carbon steel and are the most common type of b...
The most common bolt grades are Grade 2, Grade 5, Grade 8, and Alloy Steel. 1. Grade 2 bolts are made of low-carbon steel and are the most common type of bolt. They are relatively strong, but not as strong as Grade 5 or Grade 8 bolts. 2. Grade 5 bolts are made of medium-carbon steel and have a tensile strength of at least 120,000 PSI. Grade 8 bolts...
There are three main systems of bolt grades: SAE, ASTM, and ISO. 1. SAE(Society of Automotive Engineers) grades bolts according to their strength, ranging from grade 2 to grade 8. Grade 2 is the weakest, and grade 8 is the strongest. 2. ASTM (American Society for Testing and Materials)grades bolts according to their chemical composition and physica...
ASTM A307 1. ASTM A307 Grade A consists of low- to medium-strength carbon steel with a minimum strength of 60,000 psi. They’re mostly found in general, non-critical applications and are equivalent to SAE J429 Grade 2 bolts. 2. ASTM A307 Grade B consists of medium-strength carbon steel with a strength of 60,000 to 100,000 psi. They are frequently us...

Sep 11, 2023 · There are two main grading systems for bolts: the SAE system and the metric system. SAE system: The SAE system is used in the United States and Canada. The most common SAE bolt grades are 2, 5, 8, and 10. Grade 2: The weakest grade. It is typically used for light-duty applications.
This chart helps to identify the grades of bolts using the identification marks on the bolt's head along with the strength and hardness of common grade bolts. Please note the bolt heads may also include the manufacturer's identification stamp, especially with high strength bolts.
