What is the shear strength of a m12 bolt?
Grade 8.8 Bolt Loading Capacities Table
| Diameter of Bolt | Tensile Stress Area At | Shear Capacity |
|---|---|---|
| Ps | ||
| mm | mm2 | kN |
| 12 | 84.3 | 31.6 |
| 16 | 157 | 58.9 |
What is the shear strength of a 10.9 bolt?

|---|---|---|
| mm | mm2 | kN |
| 12 | 84.3 | 33.7 |

What grade of bolt has the highest shear strength?
12.9 Bolt Shear Capacity
- 12.9 Bolts. A 12.9 bolt is one of the highest grade of bolts produced. Known for their high tensile strength, they are built with both hex and Torx heads and are available in zinc or chrome finishes.
- 12.9 Shear Strength. The minimum tensile strength of a 12.9 bolt is 1220 MPa.
Is a Grade 10 bolt stronger than a Grade 8 bolt?
There are two systems of measurement here. You have SAE and the Metric system of grading bolts. SAE Grade 8 is roughly equivalent to a metric Class 10.9. SAE Grade 8 bolts are typically about as strong as you can or want to get.
Is Grade 8 or Grade 5 stronger?
Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions. Grade 8 bolts have 6 evenly spaced radial lines on the head. Grade G is roughly equivalent to Grade 8.
What is the hardest type of bolt?
Grade 8 is the hardest, Grade 5 is medium, and Grade 2 is the softest. This is the most common grade of steel fastener and is the least expensive. Grade 2 bolts have no head marking, although sometimes a manufacturer’s mark is present.
How to calculate the shear force of a metric steel bolt?
If you’re interested in the force required to break the bolt, simply substitute the Ultimate Shear Strength for Yield Shear Strength. In all likelihood though, the aluminum will tear long before you get to the point of shearing the bolt. For metric bolts the tensile strength can be calculated from the grade of the bolt expressed as A.B (eg 8.8).
How is shear strength related to tensile stress?
In general the tensile stress area and the shear stress area are different. According to EN1993-1-8 Table 3.4 the shear strength of the bolt may be based on the tensile stress area. The yield strength fyb and the ultimate tensile strength fub for bolt classes 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, and 10.9 are given in EN1993-1-8 Table 3.1 .
How to calculate allowable stress on a bolt?
Allowable Stress (N/mm 2, lbs/in 2) = Shear Stress Equation Single Shear Shear Stress Average = Applied Force / Area
What are the grades of metric screws and bolts?
Metric bolt grades and strength calculator to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9. Some notes from ISO 898 metric screw threads standards:
