If you've ever had to remove a stripped bolt or screw, you know how incredibly frustrating it can be. Normal pliers slip when trying to grip onto the screw head. Unless you're careful, you can easily make the problem worse, requiring you to drill out the screw (a dangerous proposition)
That's where these precision screw removal pliers come in. The end is concave and extra-grippy so you can grasp the bolt head and tug on it. It's sort of ingenious! Perfect for frustrating dis-assembly of electronics both old and new. Best for screws of metric size M1-M3, imperial #0 to #4
