Our daily tools require a variety of small components to be reinforced, which are essential for the composition of our various machines, but the variety of components and the names of the various components are not bad. Many, when we use it, we often need to use it together. What is the difference between the nut and the nut? How to distinguish the nut from the nut?
The difference between nuts and nuts:
1. The nut, also called a nut, is a fastener with a drive system and internal threads. It is planned to be combined with externally threaded fasteners to lock the fittings. Depending on the application and function, the edges or shapes are different. Planning and classification.
Commonly used are Hexagon Nuts, Domed Nuts, AssembleWasherNuts, HexagonSlotted CastleNuts, HexagonFlangeNuts, Hexagon High Strength Snails Hexagon High-Strength Nuts, SquareHead Nuts, Nylon Nuts, WheelNuts, Weld Nuts, Coupling Nuts, and the like.
2. The hex nut is used with screws, bolts and screws to achieve the effect of fastening the parts. Among them, the type 1 six-purpose nut is widely used, and the C nut is used for machines, equipment or structures with rough appearance and low precision requirements. The A and B nuts are used on machines, equipment or structures where the appearance is relatively bright and the precision is high. The thickness of the type 2 hex nut is thicker, and it is often used in occasions where the assembly and disassembly are often required. The thickness M of the hexagonal thin nut is thinner, and is often used when the outer space of the connecting mechanism is limited.
How to distinguish between nuts and nuts:
1. According to the wrenching structure, the so-called wrenching structure refers to the place where the screw/bolt is used to place the wrench, that is, in some systems, the externally threaded rod-shaped part of the outer wrenching structure The system is called a bolt. On the contrary, the inner wrenching structure is called a screw. External wrenching structure: Hex head bolts. Internal wrenching structure: Hexagon socket bolts, etc. This is quite obvious, for example, the fasteners in our national regulations, for example, GB5782, GB5783 (one and a half threads, one full thread). Because they are all hexagonal structures, they are called bolts in the specification.
2. Differentiate according to whether the product has non-threaded rod features. This is also a widely used classification method, which generally distinguishes between bolts and screws. That is: if the part of the product except the head is all threaded, the part is called a screw. On the other hand, if it has characteristics such as a polished rod in addition to the thread, it is called a bolt.
3, the screw is a more abstract statement. The exact material should be bolts, screws, and screw caps. Bolts and screws are round, strip-shaped objects with equidistant threads. The bolts are of flat head type. The screw is pointed at the front like a nail. It is necessary to use the bolt together with the screw cap, perhaps on an object that has been threaded. Screws are used on relatively soft or thin objects, and they are drilled with their own threaded edges. The threads on the bolts are shallow and have no sharp edges. The thread on the screw is sharper and the thread is deeper, which facilitates drilling into the object. Most bolts and screws require a more common simple thing - a screwdriver.
