8.8 Bolt

DESCRIPTION:

The 8.8 bolt is a high strength bolt and has a grade of 8.8. Currently, bolt 8.8 is the most popular bolt, widely used in many industries such as construction, machine building, mechanics, manufacturing and assembly.

The 8.8 bolt is a high strength bolt and has a grade of 8.8

What does 8.8 mean on a bolt:

The notation “8.8” on a bolt refers to its grade or strength. In the metric system, like in many European countries, bolts are graded based on their material composition and tensile strength.

Here’s what each part of “8.8” represents:

The First Number (8): This indicates the ultimate tensile strength of the bolt material in megapascals (MPa). In this case, “8” means the bolt material has a tensile strength of 800 MPa.

The Second Number (8): This number represents the yield strength of the bolt material as a percentage of the ultimate tensile strength. In the case of “8.8,” the bolt has a yield strength that is 80% of its ultimate tensile strength.

So, a bolt with the marking “8.8” has a tensile strength of 800 MPa and a yield strength of 80% of that, which is 640 MPa. This grade of bolt is commonly used in various mechanical and structural applications where a moderate level of strength is required.

Other names: bolt class 8.8, class 8.8 bolt, bolt 8.8 strength, 8.8 bolt, 8.8 bolt strength, 8.8 hex bolt, heavy hex bolts
