[QUOTE="Anybodyhome, post: 457752, member: 19161"] [URL]https://norwoodscrewmachine.com/blog/bolt-grades-know/[/URL] [HEADING=2][B]What does a Bolt Grade Mean?[/B][/HEADING] This is the most basic question for someone who is not familiar with this term. This is a technical term which determines the properties of a bolt. The grade of a bolt determines the maximum amount of stress that the bolt can handle. It also helps determine which tools are suitable for tightening these bolts. Moreover, the type of method used for tightening the bolt is also dependent upon the grade of the bolt. Therefore, it is very important to understand the grade of a bolt in order to use it properly. [HEADING=3][B]What are the Different Bolt Grades?[/B][/HEADING] There are a huge variety of bolt grades that are suitable for a diverse range of applications and environments. Let us have a look at each grade and its properties: [LIST=1] [*][B]Grade 2 – [/B]The grade 2 bolts are most commonly manufactured from low or medium carbon steel. Bolts of this grade do not have any radial lines. The bolts of this grade with a nominal size range from 1/4″ to 3/4″ have a minimum tensile strength of about 57000 psi and the yield strength of sizes from 3/4″ to 1/2″ 36000 psi. [*][B]Grade 5 – [/B]Unlike grade 2 bolts, grade 5 bolts feature 5 radial lines. These bolts are manufactured from medium carbon steel. These bolts come in two different size ranges – 1/4″ to 1″ and 1″ to 1 1/2″, which have the proof load of 85000 psi and 74000 psi respectively. [*][B]Grade 8 – [/B]Grade 8 bolts are made from medium carbon alloy steel. The bolts of this grade feature 6 radial lines. The nominal size of the grade 8 bolts can be from 1/4″ to 1 1/2″. The minimum yield strength of this grade bolt is 130,000 psi. A maximum of 120,000 psi of tensile force (proof load) can be applied to grade 8 bolts. [*][B]Grade S – [/B]Grade S bolts have the capability to withstand 45 to 49.9 MT of stress per 6.45 cm3. Bolts of this grade are heavy duty bolts that are strong and highly durable, and thus are used in a variety of heavy duty applications.
