Masonry and concrete anchors are a special type of fasteners that are designed to work with very hard surfaces. These can include masonry like brick or stone as well as concrete. While you may not need these on very project, knowing how to use masonry and concrete anchors makes New York City exterior and interior renovations easy.
It is important to consider the type of project that you are working on before you decide on a styles or types of anchors. New York City residents will find that there are several considerations that you have to keep in mind when choosing an anchor.
Basically an anchor works to either expand into the drilled hole in the hard surface or to create a hold based on friction against the edges of the hole when the screw is inserted into the anchor. There are also some types of masonry anchors that come with a powder-actuated or chemical treatment that helps to secure the anchor to the concrete or masonry surface. However, for most people doing this on their own a simple mechanical anchor that expands upon insertion will be the product of choice.
Loads to Handle
When choosing anchors for New York City projects it is important to know the total weight of the object you are fastening. This is because these fasteners are rated to hold a specific amount of both shear load and tensile load.
Shear loads are those that pull down, which is the actual weight of the item. It is the downward force that is parallel to the surface of the wall. This would be the case if you were hanging a garden hose reel or a large picture. Tensile loads are those that pull perpendicular from the anchor. This type of load would pull straight up or down from the anchor.
Stationary or Vibratory
Stationary loads are the most common types of loads requiring anchors. New York City residents will typically be working with stationary types of loads. These could include book shelves, mirrors, hanging pipes or any other number of applications.
Vibratory loads are more concerning as the item being attached will move, which can pose a problem for securing the anchor. As the item naturally moves it can cause the anchor to work loose, which may make a wedge anchor the best option.
It is important to consider both the load type as well as the size and style of anchors. New York City fastener supply stores can provide information to help you make the right selection.
