What is a concrete expansion anchor?

Expansion anchors are fasteners designed for use in masonry base material that provides holding power through expansion . There are two kinds of expansion anchors; pre-expanded and unexpanded. The pre-expanded expansion anchor is inserted in a predrilled hole compress and then exerts force to create the holding power.

Will drilling into concrete crack it?

Drilling, nailing and screwing can all cause concrete to crack if they’re not done properly .

What is the difference between anchor bolt and expansion bolt?

The anchor bolt allows a smooth screw to be stressed by mechanical locking force; The expansion bolt mainly generates friction by pressing , and the force is applied.

What is the difference between wedge and expansion anchors?

The wedge anchor can only be used in solid concrete .

Wedge anchors are designed not to be used in other masonry materials such as brick or hollow block. The expansion clip on the wedge anchor is placed on the anchor body in a manner and location that makes the expansion tolerance location critical.

How does a concrete expansion anchor work?

Once inserted into the hole in the concrete, the nut is turned clockwise. This action pulls the anchor body up , which slides the expansion clip down the cone-shaped working end of the wedge anchor. The clip is then expanded and wedges between the anchor body and the concrete.

As a rule of thumb, the space for the nut and washer is equal to the diameter of the wedge anchor being used . For example, if a 2×4 is being fastened to concrete with a 1/2” wedge anchor then the minimum length of wedge anchor would be 1-1/2”(2×4) + 2-1/4”(minimum embedment) + 1/2”(space for nut and washer) = 4-1/4”.
