Know The Basics Of Anchor Bolts

By Cindy Ingram


An anchor bolt is a kind of fastener that is used to connect structural elements or materials to concrete. Anchor bolts come in different kinds and there are different methods used to attach them into concrete. There are cast-in-place bolts and there are bolts that are built to be attached to existing concrete. These bolts can last for decades, or even centuries, when properly attached. Usually, bolts are ordered in large quantities from metal fabrication businesses.

Few Common Types Of Bolts

The A193 B7 Stud is a kind of cast-in-place anchor. While it's often used in automobile industry and mechanical engineering, it can also be used as an anchor. That is possible by casting the head of the bolt into wet concrete and exposing its threaded end. When the concrete hardens, structural elements will be attached to the bolt. They will be kept in place by using nuts and washers.

Another popular type of bolt is the L- or J-bolt. This type, as the name implies, features a bend at one end. It is used in the same manner as other cast-in-place anchor bolts. As soon as the concrete is poured, the L-bolt or J-bolt is arranged in place. When the concrete has set, other structural elements are attached and fastened together. Some prefer L- and J-bolts because of their superior grip.

To increase the integrity of bolts, manufacturers coat their products with Xylan. Xylan is a fluoropolymer topcoat that gives additional corrosion resistance and lubricity to metals. Xylan Coated Bolts, in simple terms, are smoother and more resistant to rust and heat. If you plan to build a structure that can withstand the test of time, it's just reasonable to make use of bolts with Xylan coating.

Where To Get The Bolts?

You can always hire the services of metal fabrication companies if you need standard anchor bolts. In fact, you can find a company that can provide customized bolts for your non-standard project. If you believe building structures is hard, then you will appreciate how easier it is to look for reputable metal fabrication companies nowadays.
