For an all-out supply of your repair tools and your maximum convenience, grab this flexible and agile, full-on metal screwdriver extension. It will allow you to easily take control of the spots that are difficult to reach, especially those that your hand and your central screw or drill can no longer reach. Easily mount it on top of your screw or drill. With its flexibility, it's bent-proof. Despite that, it's easy to control due to its strong solid alloy steel shaft. You have four length options for this: 150mm, 200mm, 300mm, or 400mm.
