How to Safely Use Stainless Steel Screws in Aluminum

It is no doubt that stainless steel screws are the best when it comes to holding together materials such as aluminum sheets so that when faced with a variety of elements they do not break open. However, the dissimilar nature of these two metals puts them at risk of getting corroded resulting in their destruction altogether. At Marsh Fasteners , we believe that the steel screws can be used with aluminum but some precautions must be taken if they are to work well together.

Tips to consider when using stainless screws on aluminum

  • Do not expose to water

Salty water is an electrolyte that can easily corrode either the aluminum or stainless steel material when they come into contact with each other. Therefore, it is important to always separate the two metals as soon as possible especially if the environment has salty water or anything close to it.

  • Create barriers

To reduce chances of the metals getting corroded reduce the contact the two metals have by creating a non-reactive barrier. The best barrier material is plastic washers which ensure that the metals are sealed at their point of contact. Also, to reduce their contact with water, connecting points can be protected using tape or even paint depending on your preference.

  • Check the surface area of metals

Always ensure that the aluminum part of the material is larger than the stainless steel screws to avoid it being eaten away. Aluminum which has an anodic nature will quickly disintegrate when it comes into contact with salty water, and will do the same when its surface area is less than that of stainless steel.
