## How much weight can a threaded rod support?

Weight rating of threaded hanger rods.

Nominal Rod Diameter (in) Root Area of Thread (in2) Maximum Load 1)
lb
1/2 0.13 1100
5/8 0.20 1800
3/4 0.30 2700

There are three grades within this specification, 36, 55, or 105. These grade numbers represent the minimum yield strength (ksi) requirement of the anchor bolt.

How much weight will a 1/4 bolt hold?

For example, an eye bolt with a 1/4 inch shank can typically hold up to 600 pounds at a straight pull (no angle). However, at a 15 degree angle, the maximum weight capacity drops to 480 pounds (80% of the “straight pull” weight capacity).

#### How much weight can a Grade 8 1 4 bolt hold?

Grade 8 bolts are designated as a 150 ksi. This means its tensile strength or the resistance it has before it is subject to breaking under tension is equal to 150,000 lbs. per square inch.

#### How much weight can a 1/4 lag screw hold in a stud?

That being said, I believe the dead load of the average 1/4″ lag is roughly 400# tear-out in a stud.
