Applications

1, A193-B7/A194-2H is warm with alloy steel bolt material bolts and nuts;

2, bolt: mechanical parts, with a nut cylindrical with threaded fasteners. By the head and screw (cylinder with external threads) two parts of a class of fasteners, need to cooperate with the nut, used to fasten the connection of two parts with through-hole;

3, this form of connection called bolt connection. Such as the nut from the bolt screwed down, and can make the two parts separate, so the bolt connection is a removable connection.
Screws: the use of the object's bevelled circular rotation and friction of physics and mathematical principles, step by step to fasten the tool of the machine parts.
