Q:What is the principle of screw
Screws are an example of this simple mechanical principle of the slope. Screws are like a spiral mountain road, and the more the groove is, the more effort is. The thread of the screw is a simple mechanical "spiral" application in physics, while the spiral is the deformation of the slope.
Q:What tools are used to remove the screws, the two lines are grooves, the middle of a paragraph is convex
Motor on a lot of screws on this one, one by one in the middle of a word with a knife set a trough can be used
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:What is the damage to the mouth of the screw?
First find a good tool ... tiger pliers ~ and the like ... and then forced it ... I was the last time so get ... good results ~ also exercise
Q:How to remove when the screw is not threaded
You can use a chisel in the screw cap to open a word mouth, and then use the screwdriver can be screwed down.
Q:How is the screw nailed to the wall
Use a slightly larger nail than the screw into the wall. After unplugging, use plastic expansion bolts and then screw the screws. The disadvantage is that the strength of the cement is different, and some pull the nails will not care when the wall will tear off the hole.
Q:How does the screw twist?
For the hexagonal head of the screw can be directly vibration (pay attention to strength), and then twist; if not edge of the case, you can use the saw or flat shovel of the head of the screw slotted with a screwdriver.
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:Why should the screw twist clockwise?
Clockwise tightening of the screw is called orthodontic screw, counterclockwise tightening of the screw called anti-screw or left teeth screws, the general international are clockwise orthodontic screws, in a particular case will use the left teeth Screws, such as the need to fix the fan impeller, are left teeth
Q:Screw hole slip wire how to do?
Slippery wire that has been broken thread, once the damage is not possible to repair
