# Best answer: How much shear force can a 3/8 bolt take?

Contents

Forget about shear loading, a good, commonly used bolt such as the Powers PowerBolt and its ilk will not break. A 3/8-inch bolt of this type is rated to 7,000 pounds in 6,000 psi concrete (basically granite) and 4,000 pounds in 2,000 psi concrete (hard sandstone).

## How much shear force can a 3/8 bolt take?

A 3/8 inch bolt of this type is rated 7,000 pounds in concrete at 6000 psi (actually granite) and 4000 pounds in concrete at 2000 psi (hard sandstone).

## How much shear force can a bolt hold?

The Industrial Fastener Institute (Inch Fastener Standards, 7th ed. 2003. B-8) states that shear strength is approximately 60% of the minimum tensile strength. “As an empirical guide, shear strengths of carbon steel fasteners may be assumed to be approximately 60 percent of their specified minimum tensile strengths.

## How much pressure can a 3/8 bolt handle?

Material Strength – 60,000 psi J82 60M or Grade 1 or Class 4.8

## How strong is a 3/8 lag bolt?

A lag screw measuring 3/8 inch can withstand up to 200 pounds per inch. A screw with a thread diameter of 14 inches will hold over 272 pounds.

## Are stainless bolts stronger than Grade 8?

Stainless steel bolts are rated for corrosion resistance. Bolt strength is rated in PSI (pounds per square inch). A stainless steel bolt has the same PSI rating as a grade 5 bolt (125,000 PSI). A grade 8 bolt has a stronger rating with a PSI of 150,000.

## What is the shear strength of a Grade 8 bolt?

Shear strength of a grade 8 bolt in good condition is 91,000 psi.

## 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.

## What is the shear strength of a 3/8 inch lag bolt?

A 3/8 inch screw of this type has a rating of 7,000 pounds in concrete at 6000 psi (actually granite) and 4000 pounds in concrete at 2000 psi (hard sandstone). This is roughly the breaking strength range of the carabiners and well above the rope’s maximum impact strength.
