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: Why the screw thread more closely, spin into the more effort?: Screw thread more dense, indicating the screw thread deep and shallow, the screw in the advance the resistance of the smaller, when the spin naturally more effort.

Q: What is the meaning of the 8.8 on the screw: Alina: refers to the strength of the thread level, the decimal point in front of the tensile strength, 8 is 800MPa, 10 is 1000MPa, the decimal point behind the value of the yield limit and the tensile limit ratio, .8 is 0.8.

Q: Screws are not slopes.: Of course, there are slope, as well as self-locking phenomenon, such as self-locking nut

Q: I'm talking about another thing: Screw is the use of objects of the circular circular rotation and friction of the physical and mathematical principles, step by step to fasten the tools of the tools. Screws are the general terms of fasteners, daily oral language

Q: Please understand the friends of the self-tapping nails, screws, nuts production process, is the manufacturer's process. 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 is the screw nailed to the wall: First with the diameter of the nail into the half, and then come up with that nail, then screw into the screw

Q: This screw ye use, and how to use next to the cover: This is an expansion screw. Take a suitable electric drill bit to drill a hole in the wall, and then put the sleeve into the eyes of the drill, put the screw into the sleeve, this than the ordinary screw firm.

Q: Engineering argument, usually referred to as the M3 screw, M refers to what is the meaning? The Please instruct the engineering staff.: M: ordinary thread;: screw that thread diameter (ie, the top of the thread) is 3mm, nuts that thread diameter
