Diameter (D) x Length (L) x Leg distance (C) x Thread (T) Manufacturing. This is because the working end of the anchor bolt will not fit through the hole, so you will need to size down to ensure that the entire bolt is able to fit through the opening of the fixture hole. You could also use female anchors such as the single and double expansion anchors, machine screw anchor, or the drop-in anchor to achieve the same uniform look. When the load is fastened to the wall, the load is at a ninety-degree angle to the anchor. A simple rule to remember is that the smaller the diameter of the bolt, the less the depth of the drilled hole needs to be. So, a 1/2″ anchor set with a minimum embedment of 3.5 inches will be a stronger hold than a 1/4″ anchor with a minimum embedment of 1″.

Since mechanical anchors can provide holding values based on the friction of the bolt against the walls of the hole, if the friction is broken, the holding value will diminish. The holding values will be significantly reduced the closer to the bottom of the concrete the anchor is placed because of the unsupported edge that you have created. For projects where the load is being anchored to concrete overhead and especially for heavy loads, tension is of immediate concern. However, they are two different materials with different compression strengths and reasons for being used. Masonry’s catastrophic failure goes beyond cracking.

Concrete is the stronger of the two and is used in building skyscrapers, superhighways, and dams. The grade corresponds to the minimum yield strength of the anchor bolt. These types of anchor bolts are used when the aesthetic quality of the fixture is needed and when you don’t want anchor bolts sticking out at different lengths from the installation, which can be unsightly. These loads are known as heavy load values and have a few more considerations to take place than if the load was simply resting on the ground.

The force needed to break the dried cylinder of concrete gives the PSI or compression strength of the concrete. Different types of anchors are used on different applications. Concrete is a mixture of paste, which is Portland cement and water, and aggregates or fine and coarse rocks.When it hardens around the aggregates, the paste gets much more reliable. Flat or round-headed sleeve anchors have smooth heads that protrude from the fixture and look uniform, giving a finished look to the project.
