Q:What is the invention of the screw?
Should be the 18th century Mozzley in London invented all-metal precision screw lathe. The following year, Wilkinson made a nut and bolt making machine in the United States. Both machines can produce universal nuts and bolts. Nuts and bolts can be connected together metal parts, so to the 19th century, the manufacture of machinery to build houses of wood, has been replaced by metal.
Q:What is the meaning of the screw and the 4 and 8?

Q:How do I install the screws correctly?
After we understand the characteristics of the screw, we can proceed to the next step. For example, we use the hands of a 8.8-wide hexagonal screws, then we have mastered the 8.8 hexagonal screws, the use of screws can be used to wipe some of the oil, so that we can protect the screws, in the invisible Which extended the life of the screw. And we have to use the 8.8-grade hexagon screw in the process, we will be able to know that we need to properly protect the screw head inside the hexagon, to prevent 8.8 grade hexagon screw skid, because we know 8.8 grade hexagon screw More difficult to take out. Then we can think of this screw should be used in what place? We can not put a small number of digital screws on the large industrial above, so that the screws can not withstand the pressure of large industrial above, so we need is to help the screw to choose a suitable place, so the screw on the matter The value of the.

4.8 and 8.8 refer to the performance level of the bolt. Other bolt headers are 10.9 and 12.9. The higher the level, the better the performance of both bolts. 4.8 is defined as: 4 represents 4 * 100 = 400MPa, refers to the tensile strength of bolts 400MPa, .8 for the yield ratio of 0.8, the nominal yield strength of 400 × 0.8 = 320MPa 8.8 grade bolts performance: tensile strength = 800MPa, yield strength = 800 * 0.8 = 640MPa
Q:What tools are used to remove the screws, the two lines are grooves, the middle of a paragraph is convex
