In the process industries, such as oil, gas, and petrochemicals, the selection of the right fastener in the right application can be critical. The bolts used to connect companion flanges, for example, or the screws used to connect a pipe standard to a load bearing wall, or the nuts and bolts used to connect the dished ends of a reactor are all critical to production. Picking the right fastener is also critical to safety, both for the process and for the plant workers. Picking the right fastener will not be noticed. But failing to pick the right fastener for an application may cause problems from a small leak to a disastrous failure, and that will be noticed for sure. We are going to look at how to pick the right fastener every time. Know the Application Before you call your fastener supplier, you need to know what the application is. There are so many applications for industrial fasteners that even a list is out of the scope of this paper, but the kinds of fasteners and their suitability for applications and service are often the same in many applications. Whether you use mild steel or Chrome Moly, or even something exotic will depend of the requirements of the application. You should also know how to use the standards that cover fasteners and their uses. ASTM A307, for example, covers carbon steel bolts, studs, and threaded rod up to 60,000 PSI tensile strength. ASTM F593 covers stainless steel bolts, hex cap screws and studs. ASTM A193/A193M covers alloy steel and stainless steel bolting for high pressure or high temperature service and other special applications. You can often find your application, or an application that is quite similar to your own, mentioned in these and other standards. Select the Right Type of Fastener for the Application There are some basics here. Will your fastener fit? Sometimes more than one type of fastener will appear to work. That’s where your experience and that of your fastener supplier will help you decide on the right fastener for the application. Typically, a bolt consists of a head, a shaft of some length, and a threaded end. The head of the bolt can be hex, screw head, socket head, or have another design. The design of the bolt head can be important for the amount of torque the bolt will take, and other issues, so it is important to select the bolt head properly. The length of the bolt is based on the application. For example, a flange bolt needs to be long enough to hold a washer, the flange, the flange gasket, the companion flange, another washer and the nut, with several threads left over for safety. Threads are part of the application, too. Whether coarse (UNC), fine (UNF), or 8 thread (UN—mostly used in oilfield applications) the threads need to be chosen to provide the best load handling characteristics. There are also Metric standard threads, BSW (British Standard Whitworth), and others. Thread selection is important: coarse threads will allow for quicker assembly. Fine threads take longer to assembl...

According to Grand View Research, the global fasteners industry will be worth US $104 billion by 2020 and US $120 billion by 2023. This robust growth and increasing demand for fasteners is being driven by a growing demand for automobiles, aircraft, electronic appliances, industrial machinery and medical equipment. Economic and industrial growth in countries including the US, China, Brazil, Russia, Poland and India will further increase the demand for fasteners. The US is the main destination for Taiwanese fasteners, with 40% of exports arriving there in 2015. However, the US government is currently promoting domestic production and imports are declining. Taiwanese fastener producers will need to diversify to avoid over-concentration on the US market. In 2016, the EU removed anti-dumping duties on imported carbon steel fasteners from China and Malaysia. 7 of the top 10 export destinations for Taiwanese fasteners are in the EU, therefore Taiwanese producers will now face fierce competition from the Chinese mainland. Taiwanese producers will need to control their cost structure and provide value-added services to remain competitive on the EU market. The automotive industry drives the market The automotive industry is a major driver for growth in the worldwide fastener market. The global automotive fastener market is predicted be worth US $25.9 billion by 2022 and it is forecast to grow at a CAGR (compound annual growth rate) of 3.1% from 2017 to 2022. Emerging trends that are having a direct impact on the market include the development of lightweight material fasteners and introduction of self-contained in-die fasteners. Threaded and non-threaded fasteners form the major segments of the automotive fastener market. Threaded fasteners are expected to remain as the largest segment, as they offer higher corrosion resistance and more durable bonds than non-threaded fasteners. The aluminum and plastic fastener segments of the market are predicted to show above average growth between 2017 and 2022. As for the regional market, the Asia Pacific region is forecast to experience the most significant growth in the near future due to high vehicle production levels. E-Commerce buyers elevate sales The online marketplace is making it easier than ever for global buyers to source products. The fasteners market is no exception and is taking full advantage of this sourcing method. In 2016, requests for quotation (RFQs) for fasteners on the Alibaba.com platform increased by 32% over 2015, demonstrating significant increases in purchases made online. The top destinations for these online purchases include India, Russia, Australia, Malaysia and Turkey, and they represent the truly global nature of e-commerce and the opportunities it can provide for both fastener buyers and suppliers. What are FASTENERS? Fasteners are hardware devices that mechanically join two or more objects together. Fasteners are usually composed of screws or bolts and are used to create non-permanent...
