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.
