Why is the screw divided into the Phillips and Slotted?

Screws are one of our most common industrial parts, in our daily life. Screws are everywhere, for example, we often wear watch with small screws, or desktop computer host, to the airport vehicles and other transportation tools, are essential things in people's lives, and sometimes we overhaul some things in the home, or install what works of art, are required to screw. I do not know whether you have found that it is in the market we often use screws, are divided into Phillips screw and Slotted screw, why is this? Let's let LIHAO tell you the answer.

In fact, at the beginning of the screw, the slotted screw is the first to create, and the screw also needs to create the invention out of the first time earlier than the screwdriver, at that time whether we use the head of some flat hard block, can easily screw in. However, with the occurrence of the screwdriver, the disadvantages of the slotted screw are also exposed, that is, the slotted screw has a small force area, once it is tightened, it is easy to be screwed, cannot be used twice, therefore, the phillips screw was created, compared with a slotted screw, the phillips screw is tighter, the total force area is large, it is more convenient to use, whether it is tight or loose are easy to screwed. That's something a screw can't match.

In some cases, what slotted screw can do is that phillips screw cannot be replaced, for example, the top of the screw head must be very thin, under the condition of ensuring compressive strength, the phillips screw cannot be manufactured, and the screw head is thin, can reasonably reduce the volume of tightened goods, and the top of the screw head can also be worn flat, as a general steel nail application.

And finally, that's LIHAO for today on slotted screw and phillips screw.
