Help with Load Rating

Choosing a fixing with the correct Safe Working Load (SWL) for a particular application is critical. The SWL dictates the weight that the particular fixing can support safely. The SWL has been calculated through extensive testing and will be much less than the failure load, this gives a degree of comfort (or factor of safety), for instance a coat hook with a SWL of 10kg is likely to support more than 20kg before failing.
