What are screw and bolt extractors?
| Screw and bolt extractors are tools used to extract broken, damaged, or stuck screws, bolts, or studs. | |
| Screw and bolt extractors can be operated manually using tools such as adjustable wrenches or vise pliers, and various extractors allow the use of manual screwdrivers. They can also be kept in power tools such as standard variable speed drills. |
 | Extractors can remove screws, bolts, or studs from a variety of materials, including metal, wood, and plastic. |
Why use a screw extractor? | |
 | Screws or other fasteners may rust, chip or break. They rust over time after contact with water and air. This produces an acid that causes rust. |
 | Screws can also be torn off, usually when they are inserted or removed, or when the wrong screwdriver or drill is used, which may be too small or too large. Insufficient force when driving in a screw or fastener can also expose it. |
 | The screw may be damaged if too much force is applied when screwing in. The screw head often breaks off, leaving the screw body stuck in the material. The cheaper the screws, the more likely they are to be damaged, as they will be of lower quality metals. Higher quality screws may be more expensive, but they are less likely to break. |
