Q: What is the meaning of the screw and the 4 and 8?: He means that the tensile strength of the screw minimum 400MPa, the minimum yield strength of 320MPa (tensile strength of 80%). Please refer to the national standard GB3098.1 or ISO international standard ISO898-1 the requirements.

Q: What is the difference between Chinese-made screws and US screws?: Formal manufacturers of screws from the size of the model is no difference (except small factories or workshops), the difference is mainly from the manufacture of screws and materials used in the surface of the treatment process only. Say even the Chinese exports of screws, in terms of manufacturing is also in accordance with foreign standards or contract requirements (such as the use of foreign customers specific raw materials or technology), the cost is relatively high, not the domestic market sales. Reference it.

Of course with M3 nut, the length of a move does not include the nut. Thread section length is also another specification. M6 indicates a nominal diameter of 6 mm and indicates that it is a standard pitch coarse thread.

Q: Is the tail screw? If it is mainly used in what place? If not what are they different?: Normally, it should be called drilling screws, screws are the use of the object of the circular circular rotation and friction of the physical and mathematical principles, step by step to tighten the tools of the tools. Drilling screw is the front of the screw with self-tapping the head of the wood screws. Screw is thousands of years of people in the production of common inventions, according to the application field, it is the first major inventions of mankind. Drilling screws are in recent years people's new invention, also known as self-tapping screws. Main steel for connecting between the need for ordinary or high-strength bolts, plates with self-tapping screw connection. It can not be used for metal and metal bonding.

Q: Also known as screw nails, I want to nail on the board, but there is no way to nail into the hard, how nail?: You say is a self-attack nail with a screwdriver twisted into the picture is not self-tapping is not used on the board, which is used on the expansion tube, to change the nail or wood screws, or direct use Nail nail

Self-tapping screw material can be divided into two kinds of carbon steel and stainless steel, carbon steel materials which are usually used in 1022 medium carbon steel. Usually used in doors and windows, metal. The head is the end of the end of the shape of the part of the formation of the formation of the surface.For thread forming and thread cutting self-tapping screws (self-tapping screws), the flat top buried, flat round countersunk, pan head, hexagonal and hexagonal wire Head of the most important, these five head type accounted for almost all 90% of self-tapping screws, the use of self-tapping screws (self-tapping screws) should first consider this.
