THE MOST COMMON FASTENER COATINGS

Mar 09, 2018

To obtain maximum availability from any fastener, it is often necessary to ensure that each aspect of the fastener is appropriate for the application that you want to use it. For example, if you are going to use a stainless steel hexagon cap screw for the bridge building, it will be important to ensure that the size and configuration of the screws are suitable to keep the weight of the bridge together with the vehicle or person who will I use it with.


In order to do this correctly, it is essential to understand the various factors that affect the performance of fasteners. One thing you need to figure out is that you need the coating on the fastener. This is critical because your different types of fastener coatings will affect the service life and ease of use of fasteners. In addition, there are so many coating means that different applications mean that if you are not careful, you may use the wrong one.


Some of the most popular paints include:


Zinc cleaning Zinc is one of the most common coatings for most fasteners, mainly because of its low price and protection. Mainly used to protect fasteners from oxidative damage, such as susceptible metal rust.


Therefore, this coating is ideal when a fastener will be used in damp places with great likelihood of rusting.


Gray phosphate Ash phosphate is another popular coating designed to protect fasteners from corrosion. However, it is considered to provide low level protection. This means that it is not ideally used in cases where the risk of corrosion is very high. One example is marine applications. In fact, this type of coating is ideal for use in dry settings, not where the fastener may be exposed to a lot of water. For optimum performance, such coatings need to be properly applied.


This means that when you want to pass fasteners with a gray phosphate coating, it will be wise to make sure that you buy their manufacturer who is reputable with the paint company.


Zinc Yellow This is an electrically coated coating on fasteners that provides a low level of anti-corrosion protection. It can be used for fasteners that may be exposed to water or in humid conditions.


As with the case of ash phosphate, it must be properly applied to provide the desired level of corrosion protection. When investing in stainless steel sleeve head cap screws and other similar fasteners, it is important to make sure you get the best coating for your application. Understanding common problems and how they work will help you solve problems and reduce the risk of purchasing less desirable products.
