First of all, from their diameter, the diameter of fiberboard nails includes 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 6 mm six specifications, of which 4 mm, 5 mm, 6 mm is the most common. The diameter of the drywall nail is not so many specifications, only 3.5 mm of this kind. Drywall nails and fiberboard nails have countersunk head, semi-countersunk head, round head design, the groove of the drywall nails is deeper, and more beautiful. The safety net indicates that under normal circumstances it is half-toothed, and the fiberboard screws are generally whole-tooth. The biggest feature of the drywall nail in appearance is the shape design of the horn head. If it is divided according to the thread, it can also be divided into two kinds of single-line coarse teeth drywall nails and double-line fine teeth drywall nails.
Fiberboard nails are mainly used in furniture factories, which can lock wood (including fiberboard/density board/high-density board/solid wood) very well, and many are currently used in place of wood teeth screws. Self-tapping drywall screws are mostly used to connect thin metal plates (steel plates, saw boards, etc.). When connecting, first make the threaded bottom hole of the connected piece, and then screw the drywall nail into the threaded bottom hole of the connected piece. Due to the high hardness of the thread surface of the drywall nail (≥HRC45), the internal thread can be tapped out in the thread bottom hole of the connected part to form a connection. Drilling screws generally have iron, stainless steel used on wood is generally iron material. There are two kinds of iron and stainless steel used in steel plates. Stainless steel can be divided into more than 20 varieties.
