There are only two steps to buying anchor bolts for concrete. The first step is to learn what kind of bolt is needed, and the second step is to locate a supplier to buy these from. This is easier to do than it sounds.

There are many ways to earn the specifications of the product needed. If this is going to hold something in place like a piece of equipment, the manufacturer will have specifications as to the bolt and the concrete that will hold it. If these are to hold a building to a concrete footing, the engineer of the plans should specify what is needed. Before relying only on this information, the local building codes need to be checked; each locality has its own requirements.

Bolts come in various shapes depending on the manufacturer and the type. Many manufacturers developed a proprietary design. These designs have all been tested and will hold something heavy in place while forces try to push, pull or twist it loose. Some of the common styles include a J hook or a U bolt with a threaded end or ends.

Whatever is being anchored to the concrete, specification should include the dimension of the bolt which will be half-inch, 3/4 inch, one-inch, etc.. These same instructions will include the length required including the length of the threaded end which will rise above the poured concrete floor. A requirement for material or strength is common; this information is provided by the manufactures.

These can be purchased easily online from many suppliers, home improvement stores or a building supply store. Once the specifications are known, the shopper can compare the prices from different companies and purchase from the one that fills the requirements the best.

A good rule of thumb when purchasing concrete anchor bolts is the "4 and 8 rule", which refers to the number of bolts and anchors needed for a particular job. The strength of the bolts is in large part dependent on the quality of concrete that you are going to attach the fixture to. It doesn't do any good to have some super strong bolts and anchors if the anchors can just rip right out of the concrete due to shoddy workmanship.

The "4 and 8 rule" says to get enough bolts and anchors for a load 4 times the weight of your fixture for a stationary load, and 8 times the weight of your fixture for a load that will shift or sway. This way you're sure to have all of your bases covered.

It is easy to purchase a right anchor bolts for concrete once all the details are noted.
