The corrosion resistance of fasteners is very important. Sometimes fasteners require a special coating. Zinc is currently the most commonly used coating. It provides reasonable corrosion resistance at a reasonable price. Hot dip galvanized coatings provide a greater degree of resistance and are typically used for exposure to high humidity and/or salt, such as in coastal areas. Due to the thickness of the coating, the galvanized nut must be too large. This means that unplated or galvanized nuts cannot work on galvanized bolts. PTFE or PFA Teflon is a special coating commonly used in areas where chemical resistance is required. Fasteners coated with Teflon have higher operating temperatures, lower coefficient of friction, good wear resistance and good chemical resistance. This coating is typically used where dry lubricants, low friction or corrosion resistant coatings are required. It is very important to select fasteners based on the widest corrosion resistance produced by building materials.
The level of vibration and heat (or cooling) that the fastener will expose is an important consideration in choice. In high vibration areas, it may be necessary to use the main torque lock nut. These nuts help prevent loose fasteners. Extreme changes in temperature can cause the fastening joint to expand and contract. This movement in the joint is sufficient to cause the connection to loosen.
If the equipment or pipe or flange to which you select the fastener has fastener specifications, this specification should always be followed. Otherwise, you need to know the parameters of the application and select the fasteners accordingly.
By enabling a wide range of knowledge and application expertise to help you, you can greatly reduce the difficulty of choosing the right fastener. The surge in online suppliers, the low cost of manufacturing countries, and even the true potential of counterfeit materials, have established close relationships with suppliers you know and trust. It is this relationship that you need a special fastener, because the factory is shut down, you can rely on this relationship at three in the morning. Choosing the right supplier is just as important as choosing the right materials and fasteners. Make sure your suppliers are experienced, known for quality materials, and respond to your needs in a timely manner.
