Different nails have different uses, different nails have different effects and use environment. Now, we will introduce a good fastening effect of nails, namely dry wall nails. Why does this nail tighten better?
In general, this nail is not a smooth structure. This kind of nail has a distinct characteristic in appearance. Use the angular head shape and the nail itself use the thread shape. This special construction greatly increases the bite force and friction between the nail and the connector, resulting in a better tightening effect.
In fact, these nails can be subdivided into one type: double line fine teeth, single line phase teeth, and white drill nails. These three types of nails belong to the drywall nail family. According to the specific use requirements, divided into three categories. So where does this nail fit in?
A double thread fine tooth is suitable for connection between drywall or metal keel because of its good lubricity and high impact velocity. But the thickness of these metal keels should be controlled within 0.8mm, otherwise it will be out of use. In contrast to the former, another single line coarse tooth is suitable for the connection of drywall to wood keel. For the third, from its own structural characteristics, it is more suitable for the connection between the gypsum board or metal keel with a thickness of no more than 2.3mm.
These three nails belong to the dry wall nail series and have effective fastening effect. In addition, such nails are considered important and good in fastening series. Widely used in ceiling, ceiling, gypsum board and metal connection.
The criteria for purchasing drywall nails are as follows:
1. The head should be round (this is also the common standard for all round head screws). Due to the manufacturing process, many manufacturers produce drywall nails that may not have very round heads, and some may even be slightly square. The problem is that it doesn’t fit the drywall exactly when screwed in. Concentric circles revolve around a point, which should be well understood.
2. The tip should be sharp, especially when used on light steel keel. The acute Angle of the dry wall nail is generally required to be between 22 and 26 degrees, and the acute Angle of the head should be full, without drag wire and crack. This “tip” is very important for drywall nails, because the nails are screwed in directly and there are no pre-made holes, so the tip also serves as a drilling hole. Especially in the use of light steel keel, bad end will not enter, directly affect the use of. According to the national standard, wallboard nails should be able to penetrate 6mm iron plate in 1 second.
3. Don’t play favorites. An easy way to determine if the drywall nail is eccentric is to place it on a table with a round tip and see if the threaded part is vertical and should be in the middle of the head. If the screw is eccentric, the problem is that the power tool will wobble when screwed in. Shorter screws will do.
