Q:M3 screw and M6 screw length, diameter is how much
M3 means that the large diameter (external thread is the outer diameter) is 3. 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:What is the principle of screw
Note that the pole and the screw lift angle of the screwdriver, that is, the slope is almost vertical, because the general thread angle is also 2.5-4 degrees. This is where the leverage principle is applied.
Q:No cross screwdriver, how can the screwdriver screwdriver?
Is the big nail? This is a lot of ways to find alternatives: glasses, calculators and other flat on the plane can be used to decorate the tip of the blade, be careful not to cut the hand do not cut the mirror material.
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:How is the screw to use?
1, first clear the broken screw on the surface of the sludge with the center of the center of the gun will be killed by the center of the drill and then drill with a diameter of 6-8 mm drill bit in the center of the drill hole drilling, pay attention to the hole must drill through. After the hole is drilled, remove the small drill bit and replace the drill with a diameter of 16 mm. Continue to expand the hole of the bolt and drill it through. 2, take the diameter of 3.2 mm below the use of small and medium current in the broken bolt in the drilling from the inside to the outside of the surfacing welding site to take the beginning of the bolt half of the length of the bolt can not start too long So as to avoid breaking the outer wall of the broken bolt. Surfacing to the upper end of the broken bolt and then continue to pile out a diameter of 14-16 mm high 8-10 mm cylinder. 3, after welding with a hand hammer hammer its end point so that the broken bolt along its axial vibration.As the previous arc heat and subsequent cooling coupled with the vibration at this time will break the bolt and the body of the thread Between the resulting loosening. 4, carefully observed when you find a trace of rust after the break from the fracture when you can take the M18 nuts in the surfacing stigma and the two welding. 5, after welding with a cool hot plum wrench on the nut around the back and forth twist can also be back and forth twist side with a small hammer hammer the end of the nut so that you can remove the bolt off. 6, remove the broken bolt with the appropriate tap to the fabric within the rack to remove the hole to remove the rust and debris.
Q:The cross screw of the cross screw was polished and how the screws were unloaded
You can use the pliers to turn down the twist can also be opened with a saw blade
Q:What is the difference between Chinese-made screws and US screws?
China-made screws are metric, American screws are American Standard or British
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. This is also a relatively wide use of a classification method, are generally so distinguish between bolts and screws. 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
Q:How to remove the broken screw?
Thick (5 or more) easy to handle, playing a hole with a dedicated wire on the line. Fine can be trouble, it is better to just re-drilling tapping.
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.
