How to Choose the Right Fixings and Fasteners

How to Choose the Right Fixings and FastenersFixings and fasteners have numerous applications including attaching cabinets to wall surfaces, repairing roofs, and fixing decking boards. However, since these items come in different sizes and shapes, you should select those that suit your project. Some of the key considerations when choosing fixings and fasteners include:


Some of the common materials used to manufacture fasteners and fixings include carbon steel, aluminum, stainless steel, plastics, as well as various steel and aluminum alloys. Of course, each material has its pros and cons. For instance, aluminum screws are soft compared to steel screws meaning they may not be suitable for use on hard surfaces. In most parts of Europe including the UK, ferrous stainless steel fasteners and fixings are not used in load bearing connections in order to comply with the European Technical Approvals (ETA) EN ISO 3506-4 standard.

Corrosion protection

Another factor to consider is corrosion protection because some materials used to make fixings are prone to rust. According to EN ISO 12944-2, corrosivity levels range from very low to very high depending on the surrounding environment (temperature, humidity, and concentration of salts in the air). For instance, heated buildings with clean atmospheres fall under the category of environments with very low corrosivity levels. On the other hand, industrial and marine environments tend to have very high corrosivity levels. With this in mind, go for fixings and fasteners with galvanized coatings or better corrosion protection.


When buying fixings that have rubber washers, make sure that the washer material is compatible with the walling, roofing, or accessory materials you intend to use in your project. At the same time, ensure the washers do not contain conductive carbon fillers because they are not compatible with steel products coated with zinc, magnesium or aluminum alloys.


Select fasteners and fixings that suit your project needs. This is particularly important because there are many different types of fixings including decking, heavy duty, chipboard, plasterboard, cavity, multi-use, metal, electrical, sanitary and roofing fixings.


To properly secure accessories with fixings, you need suitable anchors as well. Most of the anchors available on the market today are manufactured using metallic or plastic materials. Once again, choose anchors that suit your fastening needs.


When shopping for fixings and fasteners, consider factors such as type, material, anchors, corrosion protection, and washer compatibility. In general, fixings exposed to the elements should be made from austenitic stainless steel. In environments where corrosivity levels are low, use fixings made from martensitic stainless steel. If you intend to fasten aluminum sheeting, use stainless steel fixings.
