The selection of the correct fastener in the right application can be crucial in the process industries, such as oil, gas, and petrochemicals. For example, the bolts used to attach companion flanges, or the screws used to connect a standard pipe to a load-bearing wall, or the nuts and bolts used to connect a reactor’s dish ends are all vital to manufacturing. It is also important for safety, both for the process and for the plant staff, to select the correct fastener.
Have you thought of things you need to keep in mind before selecting the correct fasteners? Thousands of varieties of fasteners are available, built to hold thousands of different materials.
What are the things you need to consider before choosing the right fastener?
Here are some general things you need to consider while choosing the right fastener:
1. Consider the product’s primary use –
Think about what is the end-use of my product, and how is this fastener going to help achieve that use? Metal fasteners, for example, are suitable for items with enclosures that often need to be opened and closed, or sections that shift or vibrate. A product that is never opened, on the other hand, can call for an inexpensive substitute, such as plastic.
2. Check the finish of the product as per the function –
You should select a fastener finish only after the provider has understood and studied your requirement well and can guide you. According to product design, finish hardness must be selected, with metal grade and gauge thickness that suits the application. When ordering, make sure to explain the intended purpose of the fastener and to inquire about the drawbacks of the fastener to ensure that your needs are well communicated.
3. Know the specifications of the requirements –
You must also understand your unique needs in this line of thinking. The key size, material, and purpose of the fastener are determined by product design, so to dismiss this is to risk improper functioning and poor performance of the product. Besides, attention must be paid to the threads of the fastener. For example, for a design that calls for multiple threaded ones, do not purchase a single-threaded fastener.
Also, never use metal that is too heavy for your application and does not require excessive essential component tolerances or unnecessary fastener sizes to be met by your supplier.
4. Cost also needs to be considered
Finally, you have to take the expense into account. To save a couple of bucks, fight the urge to cut corners. Bear in mind that cheap fasteners can fail you in the long run, discrediting you and your products. You don’t actually have to purchase the most expensive fastener you can find, of course. Instead, clearly be discerning and weigh the potential long-term benefits and drawbacks of your selection.
Besides nuts and bolts, chemical fasteners, screws, nails, rivets, wooden dowels, dowel pins, biscuit joints, and even tapes are used for permanent or temporary fastening. If you’re planning on buying fasteners, these are the things you need to check for.
