The use of performance

If we want to use a screw, then the first thing we need to do is to understand the performance of the screw, is its characteristics, so that we can use the screw in the most correct place.Because there are many kinds of screws, among which, the performance of each screw is different, so the screw has a different use.In order to avoid the wrong use of screws, we must have a certain understanding of the performance of screws, so that we can use the screws in the most correct place.

First, let's have a look at self-tapping screws. The diameter of self-tapping screws is 0.8mm to 12mm.For this kind of screws are generally with very high hardness, self-tapping screws to be screwed into the test, is to screw into a piece of beta, and then check whether the screw hardness meets the standard, if not standard need to analyze the problem?To find a solution.

There are drlling screw, just as its name implies is general show the drlling screw tail shape, the hardness of the screw is also very strong, compared to the ordinary screw up, not only to maintain the ability is good, the connection object effect is also very strong, for the performance of the screw, are generally does not need auxiliary processing, can be directly on the object directly drill a Kong Suo into objects, use rise very convenient, not only can greatly improve the efficiency of work.This kind of drilling tail screw can be said to be the first choice of the staff in various fields.

From the above we can find that when we use screws for various screw performance is very important.

There are many types of screws, whether they are small screws for glasses or large screws for heavy electrical engineering.The precision of screw is usually 6g (grade 2, American specification "IFI" is 2A), and the raw screw used in construction is 1g.
