1. The head should be round (this is also the common standard for all round head screws), because of production process problems, the head of the Integrated Shooting Nails produced by many manufacturers may not be very round, and some may even be slightly square. The problem is that it cannot be completely matched with the gypsum board after screwing in. Is it concentric and rotates around a central point? This should be well understood.

2. The tip should be pointed, especially when you use it on light steel keel. The sharp angle of Integrated Shooting Nails is generally required to be between 22 and 26 degrees. This "point" is important for Integrated Shooting Nails, because the use of Integrated Shooting Nails does not punch prefabricated holes, but directly screw in, so the point also assumes the function of drilling through. Especially when used on a light steel keel, a bad tip will make it impossible to drill in, which will directly affect the use. According to the national standard, the wall panel nails should be able to drill through the 6mm iron plate within 1 second.

3. Can not be eccentric. A simple way to judge whether the Integrated Shooting Nails is off-center is to place the round head on the table and see if the threaded part is vertical and in the middle of the head. If the screw is off-center, the problem is that the power tool will shake when screwed in. Shorter screws are fine. If longer screws encounter this situation, the trouble will be big.
