There are many kinds of drywall nails: pin screws, wall board drywall nails, self-drilling drywall nails, pan head and hexagonal head drywall nails, etc.

1. Pin tight screws       Mainly used for penetration between thin metal plates. Its thread is common with arc triangle thread, thread surface also has high hardness. Therefore, during the penetration process, the screw can also tap the internal thread in the bottom hole of the thread of the connected part, thus forming a tightening effect.       This kind of screw has the characteristics of low tightening torque and high locking instinct, which is better than common through-wall screws and has replaced machine screws.       2. Drywall nails for wall board       Used for fastening between gypsum wallboard and metal keel. The thread is double threaded, and the surface of the thread also has high hardness. It can be screwed into the keel quickly without making prefabricated holes, so as to form fastening effect.

3. Self-drilling dry wall nails Different from ordinary dry wall nails, ordinary dry wall nails need to go through two processes: drilling (drilling the bottom hole of the thread) and tapping (including fastening and connecting); When self-drilling drywall nails are connected, the two processes of drilling and tapping will be completed in one go. It is drilled with the drill bit in front of the screw first, and then tapped with the screw (including fastening and connecting), which saves the construction time and improves the application of force. 4. Pan head and hexagonal head drywall nails It is more practical where the bit is exposed. The hex head drywall nails have higher torque than the pan head drywall nails. Countersunk head and hexagonal flower type drywall nails are suitable for places where the nail head is not exposed. Hexagonal flower type drywall nails can accept greater torque than static head drywall nails.
