When putting Phillip flat machine screws or bolts in place, one of the things you may need to watch out for is corrosion. Having rusted screws and bolts can make fastening a nightmare, especially if you are interested in removing the screws at some point in time. In addition to that, this can also have an impact on the aesthetics of the fastening, since having too many screws rusting can become visibly unattractive.
fastener corrosion
Fortunately, there are many approaches that one can take in a bid to reduce the risk of such corrosion. This is especially important if the screws and other fasteners are going to be used in an environment such as by the seaside, where such processes can occur rapidly. Some of the steps that are usually taken in a bid to control this include:


Painting over the screws
If you are fastening a material and you need to reduce the risk of corrosion on the fasteners, you can opt to paint over them. This reduces the surface area of the screw that is in contact with the air, which in turn reduces the risk of such corrosion. Of course, you would need to get such painting done in such a manner that having to unscrew the screws in future would not be a problem.
Use specialized fasteners
In some instances, you can also opt to use high quality fasteners that are designed to withstand a lot of corrosion. The fact that these are a bit expensive means that many people tend to avoid them, and instead use other means of reducing the risk of corrosion. However, when the risk of corrosion is very high and the cost of this is also very high, you would rather pay for the specialized fasteners. Well, these then turn out to be very good value for money in the long run.
Using sprays and lacquers
There are some sprays and lacquers that are designed to confer some anti-corrosive properties on the fasteners. This is one of the most effective ways of preventing this, and should therefore be considered if this is an issue you are trying to avoid. Such solutions are designed in such a manner that they are sprayed onto the fasteners before being put in place. They are usually made out of materials such as zinc, which is well known to resist corrosion.
If you are interested in using such products, it would be a good idea for you to make sure that you use a high quality one, since there are some that are not well made and will not offer maximum protection. In addition to that, it’s important that one follows the instructions of use. For instance, missing a small part of the screw could result in ineffective coating, which means that the screw might end up rusting later on.
In summary, if you are interested in using fasteners such as Phillip flat machine screws and are worried about rusting, you should know that there are many ways of avoiding the problem. The above are just a few of the things you can do to prevent it.

In 1971 I accepted a sales position at Star Stainless Screw Co., Totowa, NJ working in inside sales and later as an outside salesman, having a successful career at Star I had the desire with a friend to start our own fastener distribution company in 1980 named: Divspec, Kenilworth, NJ. This was a successful adventure but ended in 1985 with me starting Melfast in August 1985 and have stayed competitive and successful to date.
