Daily traffic jam seems to have become a "normal phenomenon", and the empty sky "road" seemed more lonely.
"Shark" future urban aircraft can not only effectively solve the problem of ground traffic jams, but also have good speed and flexibility, of course, in the future, after xxxx years. The aircraft looks like a kite flying in the sky. It can ride two people. Its special feature is its flexible tail design. It is a flying propeller facing upwards. It can also be used for landing when facing down. This saves space on the ground. The problem is How does this slender tail support this huge and heavy body? How does a wheel balance? Of course, this is not a technical issue in the future. There may be more advanced technology. Design: Anoop M.
Self drilling Screw made of 410 stainless steel, high hardness (40 Rockwell C), steel process.
Drilling screw is also very strong hardness, 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 Sue into objects, not just use rise very convenient, Also can greatly improve the efficiency of work. This kind of drilling screw can be said to be the first choice of workers in various fields.
So what is the use of drilling screws?
1 stainless steel plate, metal plate, galvanized steel plate, engineering installation.
2 metal curtain wall metal light compartment and other indoor and outdoor installation.
General Angle steel, channel steel, iron plate and other metal materials combined installation.
4, automobile, container, shipbuilding, refrigeration equipment and other assembly projects.
