Although it is a simple problem, attempting to use fasteners such as metal nuts, bolts or screws in an environment where vibration is a factor can take professional advice to resolve. This is especially important when you rely on fasteners for preserving the safety of expensive equipment or even human lives. It then becomes an absolute necessity to use anti-vibration fasteners.
To offer an example, long before blogs existed I was a young teen-ager with an exciting birthday gift. My father was good with mechanical things although he had little extra money and no real training. He had purchased an old rusted 50CC scooter for me which he fixed up himself. It was too small for him to ride so it was up to me. The first ride went fine and was a thrill. I rode it daily on the dirt roads nearby our home for some time. That little bike would rattle your teeth out but it sure was fun. One day the bike began to shimmy a bit more than usual and I had no idea what was causing it. I was also unfortunately not as close to home as I was supposed to be. I rode it back slowly and my father came out to take a look. He had used ordinary nuts and bolts when replacing some of the parts, and he found the bolts holding the engine had come loose due to the constant motion and vibration. It could have turned into a very dangerous situation, but luckily it was resolved.
There is an excellent technology available to us for a resolution. If you consult with professionals like those at Mack Fastener’s, Inc. you will learn about a technique called patching. Patching is a simple process to stop screws, bolts or other fasteners from coming loose in situations where they are exposed to consistent vibration from items such as motors and engines.
You can utilize threadlock patching by using fasteners that have been specially treated. A dot or layer of nylon is applied to the threaded area which allows the nylon solution to lock the threads tightly into the receiving threads. The appearance of the patch may be deceiving to the untrained eye as it looks like no more than a way to mark a fastener, but unlike paint or marking material the nylon is very tough. Even military organizations use nylon for many different items that must be employed in less than optimal conditions. The nylon used for patching becomes compressed so that applied counterforce forms a heavy duty metal-on-metal contact. The solution is usually a colored nylon patch making it easy to see where it has been applied although the color makes no difference in the performance of the fastener. Once the patch locks tight with its surroundings you won’t see the colored area and that tells you that it’s working as intended.
Patching is an excellent answer to the vibration problem since it is cost-effective, sturdy and works in a range of temperatures. This technique works so well that manufacturers of devices held together with fasteners will also utilize specialty nuts, bolts and threadlockers. This keeps the joined area fixed so it is impervious to loosening caused by motion or vibration.
