# What is the shear strength of a 12mm bolt?

## What is the shear strength of a 12mm bolt?

Diameter of Bolt Tensile Stress Area At Shear Capacity
mm mm2 kN
12 84.3 31.6
16 157 58.9
20 245 91.9

How do you calculate the shear strength of a bolt?

The shear strength of all bolts = shear strength of one bolt x number of bolts • The bearing strength of the connecting / connected plates can be calculated using equations given by AISC specifications. The tension strength of the connecting / connected plates can be calculated as discussed earlier in Chapter 2.

### How much shear can a bolt take?

The shear strength of a bolt is a measurement of the minimum amount of force needed to break the bolt into two pieces. The shear strength of a metal bolt is approximately 0.6 times its tensile strength. A bolt commonly shears where its head meets the threads.

How is bolt strength calculated?

Take the minimum tensile strength in psi of the ASTM grade, multiplied by the stress area of the diameter. This formula will give you the ultimate tensile strength of that size and grade of bolt.

#### How much weight can a 12mm bolt hold?

M10 3,370kg 5,630kg
M12 4,890kg 8,180kg
M16 9,100kg 15,200kg
M20 14,700kg 23,800kg

How is thread shear area calculated?

fed-stdh28 standard. Maximum minor diameter of internal thread. Minimum pitch diameter of external thread….Shear Area For Internal Thread.

En max = Maximum pitch diameter of internal thread.
n = Number of threads per inch

## How much weight can an M12 bolt hold?

M8 2,120kg 3,040kg
M10 3,370kg 4,810kg
M12 4,890kg 7,000kg
M16 9,100kg 13,000kg

What is the best bolt for shear strength?

Grade 8 bolts exhibit greater tensile, yield, and shear strength as well as greater fatigue resistance and, just as important, are capable of greater torque specs and therefore much greater pre-load and clamping strength.

### How much shear force can a screw hold?

A typical range for proof strength for steel is 50 to 100 kpsi (i.e., a screw with a 1 square inch cross-sectional area of steel can hold up to 50,000 to 100,000 pounds).
