Screw and bolt extractors are tools used for removing broken, damaged or embedded screws, bolts or studs. | |||
 |
Screw and bolt extractors can be manually driven with tools such as adjustable spanners or vice grip pliers and various extractors allow hand screwdrivers. They can also be held in power tools such as standard variable speed drills. | |||

Extractors can remove screws, bolts or studs from a number of materials including metal, wood and plastic. | |||
Why use a screw extractor? |
||||
 |
Screws or other fasteners can become rusty, stripped or broken. They become rusty over time after being in contact with water and air. This forms an acid that causes rust to occur. | |||
 |
Screws can also become stripped, usually when inserting or removing them, or using the wrong type of screwdriver or drill bit, which may be too small or large. When inserting the screw or fastener, not putting enough force against the screw can also cause it to become stripped. | |||
 |
A screw can become damaged when applying too much force when inserting. The head of the screw will often snap off leaving the body of the screw embedded in the material.The cheaper the screws the more likely they are to damage because they will be of lower quality metals. Higher quality screws may be more expensive but they will be less likely to damage. | |||
