A fastener is used to bind two or more objects as one mechanically. However, it has circled around the internet as to which of the two types, plastic and metal, is more useful. To end that stupid debate, both are beneficial in its own way. Commonly, people use and are more familiar with the metal one. What the public should know is that the latter is just as important as the next one.

The metallic, which is composed of steel, has a tighter force of binding unlike the other one. However, both are capable of doing the same task. The only difference is the latter is not as strong. Anyone should be given the opportunity to take time and learn about the strengths, facts, and functions of plastic fasteners.

Let us start with the basics. They are created through using a molded and tough nylon. These are built that way to resist abrasion, chemicals, corrosion, and vibration. A surprising fact is that these are just partly made of plastic. Glasses and filler metals were placed too in order to become tougher.

Circuit boards have this type of fastener. Circuit board hardware has been actually used to give guidance, security, space, and support of all electronics. They will be used to a process called electrical insulation. It would not happen using a metallic due to a reaction with the panels of this board.

A fastener can be weakened with the presence of the rust which is followed by corrosion. Therefore, metals are at a disadvantage once made in contact with water since rusting occurs. The only ones resistant to water are platinum, palladium, and gold. The reason why the plastic has gained prominence is because this prevents rust in which projects in watery areas are dependent with. Moreover, they can also withstand electrical as well of heat sensitive applications for they are nonconductors.

Plastics are resistant to ultraviolet rays and some experiments proved that several managed to be up close and personal with the sun in the solar system. These fasteners were used in the International Space Station and the Hubble Space Telescope. What was found is the ultraviolet energy being absorbed by plastics tend to react the photons that create free radicals. However, not all can survive the sun exposure.

Another huge advantage is that they are useful to soft objects. Most engineers utilize these for acid and chemical resistance, water tolerance, and nonconductivity. This dominates the metal for the metal only works for hard objects.

Plastics may not have the force as that of the latter but what can be made possible is that there has been a way to give them more force. A person can create a rust and UV resistant component once they will be in combination with the steel core that has enough presence of a steel. We can conclude that the two types are worthy competitors.

Once you happen to have a related project, always try to evaluate what you really need to have. Solve things out if strength is what you need or not. Check out if nonconductive and noncorrosive properties shall also be important. The key is everything has varying characteristics and functions but it is always up for the user on what to pick. Simply, handle things well.
