Q: What is a screw? What is a nail? What is the concept? What is the difference!: Machine nails are mechanical bolts, mainly due to mechanical connections, due to smaller size mechanical screws

Q: Screws, bolts, screws, what is the difference between the three ah?: The screw is an incorrect call, non-professionals on the threaded parts collectively, in the industry without this call. In the fastener industry, in fact, screws and bolts are not a strict sense of the distinction. However, there are two ways in the industry to distinguish between screws and bolts: 1. According to the structure, the so-called twist structure, refers to the screw / bolt used to put the wrench above the place, that is, In some systems inside, the external pull the structure of the external screw rod-shaped parts are all called the bolt, on the contrary, will pull the structure called screw. This is a more obvious example is the Chinese national standard fasteners, for example, GB5782, GB5783 (a half thread, a full thread), the hexagonal bolts, The Because they are hexagonal structure, so, in the standard name, all called: bolts. 2, according to whether the product has a non-threaded bar features to distinguish.

That is, if the part of the product other than the head is threaded, this part is called a screw. On the contrary, if, in addition to the thread but also has a light rod and other characteristics, called the bolt

The more specific the more detailed the better: According to the screw nut and thread size custom the corresponding mold, mold is done into the material, then the head - rubbing - surface treatment - the packaging is complete.

Q: How to look at screw models: When you buy a certificate. The The Written above. The The I do not know any other way

Q: Why do some nuts and washers, and some nuts without washers: General screw diameter and the diameter of the fastening parts of the hole is not large, the nut and parts of the contact area is relatively large, you can not add a gasket
