The small round hole at the end of the screwdriver has so many powerful functions that many people still don't know how many screwdrivers like these are available in every household, such as single letter ones and cross shaped ones. These screwdrivers also have many hidden tricks, so let's learn together.

I don't know if you have noticed that each type of screwdriver has a small hole on top, right at the end of the handle, with these round holes being oval shaped. The shape and size here are also different. Some friends think that the small hole above is convenient for us to hang on the tool rack, but in fact, it can play a great role when we tighten the screws.

The first function is that some friends like to purchase bookshelves and desks online. When assembling, they may encounter these hexagonal screws with inner lines, and the screwdriver made by the manufacturer is relatively short and small, making it difficult to tighten the screws when breaking them by hand, and sometimes causing hand injuries. Actually, this little annoyance is easy to solve. It comes in handy as our family's screwdriver.

At the end of the handle of the screwdriver, we can see a hexagonal hole. We just need to add a hexagonal screwdriver and extend it into the small hole at the end of the handle of the straight screwdriver. Then, we can use the lever principle to easily clamp the screw, and it doesn't require much force. The screw will tighten too tightly. Is it very practical? Next time, you can also try this method.

The second function is that when tightening screws in our daily lives, whether it is a flat head screw or a cross head screw, when it is tightened to the back, it is easy to tighten the screw with bare hands. At this time, we can also insert another screwdriver into the circular hole at the end. This turns into a simple T-shaped screwdriver. It's really easy and labor-saving to tighten the screws like this, and it can strengthen and fit better. The bookshelf and desk tightened like this are very stable when used normally.

The third function is that if you cannot find a wrench or pliers when twisting the iron wire, this round hole can also help you easily solve this problem.

Unexpectedly, the circular hole on the handle of the screwdriver still has these functions. Have you learned?
