What is a screw extractor and how does it work?
A screw extractor is a tool designed to remove screws that have become stripped, damaged, or stuck due to over-tightening, rust, or other factors. It works by drilling a small hole into the center of the screw and then using a specialized bit to grip the screw’s remaining threads, allowing for safe and controlled removal. The extractor’s unique design enables it to apply even pressure around the screw, reducing the risk of further damage to the surrounding material.
The screw extractor’s effectiveness lies in its ability to target the screw’s core, where the threads are typically still intact, even if the head is stripped. By drilling into this core, the extractor can establish a secure grip on the screw, making it possible to remove it without causing additional damage. This is particularly useful in situations where other removal methods, such as using pliers or a wrench, may not be effective or could potentially damage the surrounding material. With a screw extractor, users can confidently remove stripped screws and restore their projects to working order.
