Breakaway Screw

A breakaway screw is a screw whose head is so worn or damaged that it is difficult for the tip of a screwdriver or the tip of a drill to grab the screw to turn it.
The “drive” of a screw—its recessed seat—can be damaged by turning the screw in and out repeatedly or overtightening it.
When the drill head sticks out of the head of the fastener, it will usually rotate hundreds of times before you release the trigger. As the drill continues to rotate without being securely fixed in the screw hole, it removes metal fragments. Do this long enough and you’ll end up with a loose screw that will be harder to grab with a screwdriver/drill, so twist and pull it out.
Use the correct drill size for your screw. You might think this is easy, but a lot can happen because someone uses a screwdriver bit that is either too big or too small for the screw socket. To ensure a proper lock between the drill and the screw, use the correct size drill!
Get rid of the broken driver. As for using the correct size bits for your screws, discard old, worn out screwdriver bits. When slightly worn, it loses its ability to securely lock the screw and causes the cam to come off.
If you notice severe sticking when driving screws, try getting a new drill bit. This might be just what you need.
Apply sufficient and constant pressure. When driving a screw with a drill, you don’t want the drill to spin as fast as you can, but you do need to apply enough force. This will help prevent the screwdriver from popping out of the head of the screw, which will prevent the screw from bulging and falling out.
Create a pilot hole. Construction screws usually go into wood as smoothly as butter. But sometimes, when you drive a screw into wood, the screw gets stuck, causing a bulge. To prevent this, drill a pilot hole for the screw. Find a drill that is slightly smaller than the screw and drill a hole. Insert the tip of the screw into the hole and tighten.
In addition to reducing the bulge (which causes the screw to peel off), drilling pilot holes can also help prevent splitting of the wood when the screw is driven.
Use a bit holder. The bulge can be caused by misalignment of the screwdriver bit in the screw hole. You want to align directly with the screw axis; if you have an angle bit, you don’t get a lock, you get a cam.
To align the drill and screw heads, consider using a drill holder instead of inserting the drill directly into the drill collet.
Use Torx construction screws. Phillips screws are easier to remove due to the design of the drive. According to Handyman’s World, the Phillips slot of a Phillips head screw “tapers towards the center, like the tip of a screwdriver. When the screwdriver is turned, a force is applied from the side that pushes the tip out.”
If you want to avoid the bulge that often occurs with Phillips screws, consider using Torx screws instead. Torx screws have a star slot and require a Torx screwdriver to drive them. They provide better retention and less chance of protrusion, which reduces the chance of screw detachment.
