If you need a high strength fixing for going into a solid wall, or into a concrete floor, then you really need to be looking at anchor bolts. They come in a variety of sizes starting from small ones that may be used for holding up a shelf that is going to be used for a heavy load, through to very large ones that are ideally suited to situations where they may be subjected to a high load in a variety of directions from time to time. An example of this would be using them to anchor down a metal bracket for locating a fence post on to a concrete surface.
When it is very windy the fence will place a high load on the fence post, and hence the bracket may be trying to move in several different directions due to the wind. In this situation the anchor bolt is the ideal thing for the job due to its strength.
Heavy Duty Drill
They consist of two parts, the bolt and the anchor itself. You simply drill a hole into the desired surface, place the anchor in the hole, place your fixing over the anchor, then place the bolt through your fixing (Such as a metal fence post base) and tighten it. This then causes the anchor fixing to expand in the hole securing it very firmly in place. Being metal and due to their size, they are far stronger than a screw and a rawl plug as an example.
The next type of very heavy duty fixings, for serious applications such as those commonly found in the building industry, are chemical resin anchors, these are used where the ultimate in anchoring fixing strength is required.
They are a two part mix, based upon a resin and a hardener. They are mixed together and poured into a hole (Commonly in concrete) with the fixing, such as a bolt or eyebolt being placed in the mixture. When the resin has set it actually forms a stronger bond than the substrate it has gone into. Care obviously has to be taken such that the fixing is kept upright until the resin has fully set.
Resin based anchors are now widely used in a range of applications where the bolts had previously just been set directly in to the concrete. They are now used extensively for studwork fixings in the building industry. They are now very easy to use with the earlier systems being somewhat messy to use.
