Because there are many kinds of screws, it is important to choose the right one for the job you are completing. In addition to choosing the right kind of screw, it is also important to learn how to use it properly. Self-drilling screws are often used in projects that involve metal. As you work with this type of screw, you may encounter several problems. Understanding these problems and the causes can help you troubleshoot the issue.
Splitting
If you are having trouble using these screws, look closely at the drill end. If you notice the metal has split in the end, you will need to use new screws. However, it is important to learn why it happened to ensure it doesn’t occur again. This split is often caused by using too much pressure when you are inserting the screw. This often happens because individuals are nervous about not pre-drilling.
Outer Corners Melted or Worn
Another common problem with self-drilling screws is worn or melted outer corners. If you identify this problem, check the RPMs on your drill. If it is turning too quickly, it can create excess heat that will melt or wear out the corners of the drill end of the screws. This will reduce the effectiveness of your screws.
Chipped or Broken Edges
If you are experiencing chipped or broken edges on your screws, you may need to ease up on the use of the drill. Like a split point, this problem is caused by pressing down too hard when you are inserting the screw.
Melted Point or Reduced Diameter
When you look at the end of your screw and notice it has a melted point or the diameter is reduced, you are experiencing one of several problems. This issue could be caused by too much force like some of the other issues or it could be caused by working with materials that are too hard or there is insufficient chip clearance.
As you work with self-drilling screws, it can be useful to know what could be causing problems with the screws. Finding the right solutions will keep you from damaging too many screws before you get one to complete the job. Looking at each screw after it is damaged can help you identify the cause of the damage so you can do things differently next time.
