What Are Rawl Bolts?

Just about every do it yourself handyman must have heard of rawl bolts. They are one of the most popular fastenings available in a hardware store. Here’s an article about rawl bolts, just for those who do not know anything about them or perhaps wish to know more before deciding to make use of them.

Rawl bolts are and expanding shield anchor fastener. This means that there is a sheath around the bolt which expands once the bolt is actually inserted right into a hole to make certain that it stays there. It may be described as a general purpose anchor with a decent load capacity and a great tolerance to variance in hole dimensions.

It is most suitable to make use of rawl bolts in brickwork, stone or concrete. There are surfaces that provide the most grip area for the expanding sheath of the rawl bolt.

A few of the features of rawl bolts include a projecting stud on which to support any fittings you may wish, providing of courses they do not surpass the load capacity of the rawl bolt’s specs, a ferrule which indicates the correct size of the hole for that bolt to be inserted into for maximum efficiency, pressed steel sections which ensure that the dimensions of the hole and bolt are constant and the optimum taper nut position which will allow for optimum expansion of the sheath in all substances.

The installation instructions are pretty straightforward. All you have to do is actually drill a hole in the surface which is of the size indicated on the ferrule of the rawl bolt. Do note that if you are drilling into brickwork you should avoid mortar joints if possible. After you have a hole of the proper diameter, you should clean all of the debris out using a brush and pump. This really is to ensure that the actual rawl bolt is going to be clamping on the actual surface and won’t be in danger of sliding on debris and dirt. After this you remove the nut and washer from the rawl bolt and place the anchor into the hole you have drilled. Place the fixture over the thread. Then all you have to do is actually add the washer and nut and tighten them to the torque recommended for the bolt and fixture.

The one thing yuo really should think about is you need to have a rawl bolt which is sufficiently strong to handle the weight you are going to be putting on it. If it is too weak, the anchor will simply pull out of the wall and allow you fixture to come crashing right down to the floor.
