Concrete stud anchors are manufactured out of a number of different types of materials or coatings that are used in different types of applications.
The concrete stud anchor dimensions are described as the diameter of the concrete stud anchor as well as the length of the concrete stud anchor. The available sizes are shown with the diameter first and then the time's sign (X) and then the length for example 3/8" x 5" would describe a concrete stud anchor that is 3/8" in diameter and 5" long.
Diameter - the diameter of the concrete stud anchor refers to the tread end and the diameter of the nut that can be threaded onto it.
Length - the length of the concrete stud anchor is measured as an overall length from one end to the other, including the threads and the clipped area of the stud.
The diameter of concrete stud anchor to use in any particular application is dependent on many factors, such as the weight of an object being fastened, depth of embedment, the strength of the concrete, the diameter of the hole in the item being fastened whether or not the diameter has been specified by an engineer. The larger in diameter the concrete stud anchor is the more weight it is able to hold and the deeper the embedment the better the holding value may be attainable.
The higher the strength of concrete that the concrete stud anchor is placed within, the higher the potential holding values will be. The predrilled hole in the fixture may also be a determining factor if the hole in the fixture is a certain size than the diameter of wedge anchor that can be used is limited to the size of concrete stud anchor that will fit through the hole. An engineer for the company of the item being attached determines many types the diameter of concrete stud anchor.
The minimum length of concrete stud anchor to use is determined by adding the thickness of the material being fastened to the minimum embedment for the diameter of concrete stud anchor, plus space for the nut and washer. Each diameter of concrete stud anchor must be installed into the concrete at a minimum depth of embedment.
The diameter of the hole that must be drilled into the concrete must be equal to the diameter of concrete stud anchor being installed, 5/8" concrete stud anchor requires a 5/8" hole.
The hole must be drilled a minimum of 1/2" deeper into the concrete then the concrete stud anchor will penetrate. This will ensure that the concrete stud anchor will not bottom out in the hole and will allow space for any dust that is created during the installation process to fall into making sure it does not affect the installation of the concrete stud anchor.

As with any anchoring project, it is important to keep safety in mind and follow instructions carefully. Always remember to wear safety goggles, handle all tools with extra care and follow all technical specifications. This article is meant to serve only as a basic explanation of concrete fasteners. Always refer to manufacturer's instructions or consult a contracting expert during any anchoring project.
