Introduction of self-tapping nail
Self-tapping nails are used, which have high loosening ability and can be generally loaded and unloaded, without large and small holes and tapping. Ordinary screws in our life are generally flat-headed, with little difference in thickness and size. Self-tapping nails do not need to drill holes in working teeth, and the screws are different from those in peacetime. The pitch of self-tapping nails is a little larger than that of ordinary screws, and the head is pointed.
Classification of self-tapping nails
There are many kinds of self-tapping nails, and the varieties of self-tapping nails are distinguished by the different heads of self-tapping nails It has round head, flat head, top column head, hexagonal head and so on. Among them, the round head self-tapping nail is common in the past, while the flat head self-tapping nail is a new design to replace the round head, with a larger head. In order to give full play to the driving role of torque, the edge of the flat head is also characteristic.
Because of the depth of the groove, the diameter of the top pillar will be smaller, which will increase the pressure and can be closely combined with the flange and flange. Hexagon head is a kind of torque effect, which is characterized by trimming sharp corners. In fact, self-tapping nails can also be classified according to groove type, including inclined groove head, cross groove head, slotted head and eleven-character composite groove head.
