What Causes Screws to Break?
Broken screws are a common problem for even the most seasoned do-it-yourselfers. It can be maddening to try to remove a broken screw. It also takes time, patience, and concentration.
The Wrong Screw
The most common reason a screw breaks is because it is the wrong type of screw for the application you are working on. For instance, you should not use a drywall screw when building cabinets or installing hardwood shelving. Using the wrong type of metal screw, such as an aluminum screw, for wood construction on wood that is very heavy can lead to breakage.
Too Much Pressure
Putting too much pressure on a screw when using an electric screwdriver is also another common reason for a screw to break.
By understanding why screws break, you can prevent it from happening.
