In daily life, we often mention bolts, screws, screws, studs, nuts, nuts, etc. Do you know what the difference is? In fact, the standard saying is that there are no screws or nuts. Screws are just commonly known, as long as they have external threads are called "screws". The nut is also commonly known, and the standard statement should be called a nut (and the shape of the nut is usually hexagonal, and the inner hole is an internal thread, which is used to cooperate with the bolt and reinforce the related parts)

Standard fasteners are divided into twelve major categories, which are determined according to the use occasion and function of the fastener when it is selected. The following mainly introduces four standard fasteners: bolts, screws, nuts and studs.


Standard fastener bolts: cylindrical threaded fasteners with nuts. It is a type of fastener composed of a head and a screw.It needs to be matched with a nut to fasten and connect two parts with through holes.This form of connection is called bolt connection (bolt connection is a detachable connection ).

Standard fastener screws: commonly used in machinery, electrical appliances and buildings, etc. The general material is metal or plastic, which is cylindrical, and the grooves with irregularities on the surface are called threads. The screw is mainly used to join two objects, or to fix the position of an object. The screw can usually be removed or re-tightened at will without compromising its effectiveness. The diameter of the top of the general screw is large, such as round, square or regular hexagon, and the most common groove pattern on the top is a font, cross and square.

Screws

Standard fastener nut: a metal part used for fixing, with a hole in the middle and a thread on the inside. Nuts are often used for screws that match their size to fix their associated joints. The nuts are mostly hexagonal, followed by squares.

Nuts

Studs of standard fasteners: a type of fastening metal parts with no head and only external threads on both ends. When connecting, one end must be screwed into a metal part with an internal threaded hole, the other end passes through a metal part with a through hole, and then screw on the nut to make these two or more metal parts firmly connected A whole.
