Q:How is the screw nailed to the wall
Use a hammer to make a hole in the wall, and then plug a plastic expansion tube, the last screw.
Q:What does the screw m4x6 mean?
M for the flat wire (not self-employed screw) 4 for the diameter, 6 for the length. Units are generally millimeters
Q:Screws, bolts, screws, what is the difference between the three ah?
There are no hexagonal head but the middle of the screw with the middle of the pole known as the double-headed bolts (studs), the whole body is screw called screw, in addition to countersunk head neck bolts, T-slot bolts, anchor bolts, U-shaped bolts. Bolt tightening device for the torque wrench, the opening size of the various shapes of fixed wrench, the opening variable size of the movable wrench, hydraulic tight bolts need hydraulic pumps and other accessories. In short: fasteners with screwdrivers and hexagonal tools are screws, and fasteners with wrenches are bolts. Note: can not be distinguished by the size and length of the nominal diameter. For example, a M48 long 300mm cylindrical head fasteners, GB / 70.1-2008 standard will be defined as hexagonal head screws, not bolts.
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:How is the screw produced
The In twist
Q:How much is a screw?
To see what screwdriver, if it is a small screw, and then you buy more words, a single cost may be a few cents, if it is a single purchase may be more expensive.
Q:The Symbolic Meaning of Screw
Although small, but plays a decisive role. The role of a person, for the cause of the revolution, as a machine on a screw. The machine as a result of the connection of many screws and fixed, only to become a solid whole, can be able to operate freely, to play its great ability to work. Although the screw is small, its role is not underestimated. I would like to make a screw hello forever. Screw to regular maintenance and cleaning, it will not rust. People's thinking is the case, to always check will not go wrong. - Lei Feng April 17, 1962 diary excerpts
Q:Engineering argument, usually referred to as the M3 screw, M refers to what is the meaning? The Please instruct the engineering staff.
International Metric Thread System: The national standard CNS adopts the thread. The crest is flat and easy to be turned. The tooth bottom is rounded to increase the thread strength. The thread angle is 60 degrees. The specification is expressed by M Metric thread can be divided into two kinds of coarse and fine teeth, such as M8x1.25 (M: code: 8: nominal diameter .1.25: pitch).
Q:What is the meaning of the 8.8 on the screw
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:The screw is too tight not how to do it
Suggested the following methods: First, to the market to sell gold groceries to buy sets (about 5-6) Hexagon screw wrench, about 5-6 dollars.
