Here are a few of the myths that apply to fixings in general and occasionally the purchase of Fischer fixings specifically:
- you can buy any fixings you need in the large DIY warehouses. In fact, some forms of specialist fixings may be extremely difficult to find in large DIY warehouses – even those that have substantial trade-only sections. That might be particularly the case if you are looking for things such as certain types of high performance fixing. It might be necessary to go to specialist providers or a Fischer fixings agent;
- it doesn’t really matter what type of fixing you use providing it’s big enough. This is one of the most commonly heard misconceptions around and also potentially one of the most dangerous. The fact of the matter is that fittings are designed to do a specific job in specific materials. Simply selecting one that appears to be big and robust enough for the job might lead you into difficult situations;
- the major DIY warehouses can supply expert advice and guidance. In reality, that might be the case but perhaps more commonly it might not be. Just a sheer glance at the variety and numbers of different items sold across different product ranges in a major warehouse might tell you that statistically it is unlikely that each individual member of staff can possibly be an expert in every area. Selecting the wrong type of fixing might not only be inconvenient and expensive but potentially also highly dangerous. That expert advice might be worth having and that is another argument for going to specialist providers;
- resin fixings are replacing conventional steel and other fixings. No, they are not! There are several different forms of resin fixing and they may have a significant role to play in certain situations – notably where you are trying to avoid fixture expansion in the substrate. However, in other situations the strength and versatility of steel may be required and there are also other materials that may be advantageous in other situations;
- it’s easy to calculate the maximum load on the fixing. To be fair, this is partly true but you do need to know what you are doing. For example, the forces that act on the fixing may be significantly different from one application to another. In order to understand the type of fixing required, it is necessary to understand things such as the difference between sheer and tensile forces (etc.). If you do not understand these and related issues, calculating the load on the fixing and the type of fixing required, might prove to be more complicated than you suspect.
In the final analysis, only you can decide whether to go to a specialist fixings provider or a general DIY type outlet.
Before making your final decision, it might pay to think carefully about some of the above issues.
