What is the difference between a nut and a bolt?

The stud is the fastener used to match the nut. Nuts are parts that tightly connect mechanical equipment. Nuts are parts that tightly connect mechanical equipment. Through the threads on the inside, nuts and bolts of the same specification can be barrel nuts screw connected together. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in the nut Among them, M4 means that the inner diameter of the nut is about 4mm, and 0.7 means that the distance between the two threads is 0.7mm); the nut is the nut, which is screwed with the bolt or screw.

Bolts: mechanical parts, cylindrical threaded fasteners with nuts. A type of fastener consisting of a head and a screw (cylinder with external thread), which needs to be matched with a nut to fasten and connect two parts with through holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Bolts and nuts are a set of threaded fasteners. It is manufactured using the principle of labor-saving inclined plane. As shown in the picture, the nut is internally threaded and the thread is concave. The bolts are externally threaded and convex. The pitch and profile (angle) of the matching internal and external threads are the same. Their nominal diameters are also the same. Only in this way can they be screwed together to play a fastening role.
