Anchor bolts have long been a staple of the home improvement world. They are used to connect the different parts of a house together in order to prevent them from moving out of place due to constant movement. A well chosen anchor will help keep your foundation stable and make sure that your home stays standing the entire time that you are living there. These are used on just about every type of foundation, but for many people they are still unknown.
A stud concrete anchor bolt is basically a single, thick, cement anchor that, when installed in the concrete, actually has a threaded end sticking out from the actual concrete. The good news is that most of these concrete anchor bolts will work very well. Stud concrete anchors are typically manufactured out of hot-dipped or standard zinc-plated galvanized steel. They will be rated either a high or low security setting depending on the amount of reinforcement that they provide.
There are a few different types of anchor bolts that can be used in the construction field, but the most common are the threaded steel bolts. They are available in one end - either threaded or non-threaded - and in two different styles. The threaded version will generally require a stainless steel washer, a nut, and a washer of a different metal thread. The non-threaded version will be made from a stripped steel nipple and a washer of another metal thread.
Anchor bolts are also available that use a shear as an attachment to the steel. These shear nuts are very similar to studs, except they use a shear as a way to attach the two pieces of steel together instead of the more traditional nut and bolt pattern. Shea nuts are best used when you want a fastener that does not require extensive drilling to install; for these fasteners, a shear ring is usually used. You will need to have a reliable shear or nail and a diamond-tipped drill bit if you are going to use one of these screws in a building that has cracks or openings in the walls.
A stud is another fastening option that you might encounter when working with anchor bolts. In some cases, a stud is simply a drilled hole that is located into a wall so that an anchor bolt can be placed into it. However, the studs that are used as an anchor bolts in a building are actually built out of a steel plate that is inserted into a hole that is already in the wall. It is important that you select a stud that fits your building well, because poorly-fit studs can cause the entire wall to bow. A stud will need to be drilled directly into the wall, although this is less commonly required now that most studs are built with threaded rods that can be locked into place with washers and bolts.
An important consideration when using these anchor bolts is whether or not you should thread one end of the bolt through more than one piece of drywall or other material. For example, you should make sure that you don't thread the bolt through the top of a drywall jigsaw because the bolt could break off, causing a hole in your drywall. In addition, if you do thread the bolt through more than one piece of material, the end you want to thread should be able to fit through the holes in the material without breaking. This ensures that the bolt doesn't slip as you try to tighten it down.
