What are Common automotive metric fastener grades?

Common automotive metric fastener grades include 8.8 and 10.9. These grades indicate the strength and hardness of the fastener, with 10.9 being stronger and harder than 8.8. It's important to use the correct grade of fastener when working on vehicles to ensure safety and reliability.


Difference between 10.9 and 12.9 tensile bolts?

Grade 10.9 bolts or capscrews have a minimum tensile strength of 1040N/mm2 and a hardness of 320 - 380Hv10. Grade 12.9 bolts or capscrews have a minimum tensile strength of 1220N/mm2 and a hardness of 385 - 435Hv10. The 12.9 fastener is therefore a higher grade (hardness and tensile strength) fastener compared with 10.9 grade


What is a grade 8 nut?

A grade 8 nut is a type of fastener made from high-strength steel and is typically used in applications requiring superior durability and resistance to shear and tensile forces. It is often paired with grade 8 bolts, which have a minimum tensile strength of 150,000 psi. These nuts are usually marked with six radial lines on the top surface to indicate their grade. Commonly used in heavy-duty applications, grade 8 nuts are suited for automotive, construction, and manufacturing industries.

What is EN Equivalent steel grade for Gr 8.8?

The EN equivalent for steel grade Gr 8.8 is typically classified as 8.8 in the ISO standard, which indicates a tensile strength of 800 MPa and a yield strength of at least 640 MPa. In the European standard, this is often represented as a structural bolt or fastener made from carbon steel, usually with a property class of 8.8. This classification falls under the EN 15048 standard for structural bolting.
