The difference between Ecological Board Nail and drywall nails
First of all, from the perspective of diameter, the diameter of Ecological Board Nail consists of six specifications: 3mm, 3.5mm, 4mm, 4.5mm, 5mm, and 6mm, of which 4mm, 5mm, and 6mm are common. The diameter of drywall screws is not so many specifications, only 3.5mm. Both the drywall nails and the Ecological Board Nail have a sunken, half needle, round head design, with the drywall nails having a deeper groove for a better look. The guard net is generally a half tooth, and the Ecological Board Nail is generally called a transposition. The appearance of drywall screws is characterized by the shape design of the trumpet head. According to the thread, it can be divided into single-line coarse-toothed wall screws and double-line fine-toothed wall screws. Ecological Board Nail is mainly used in furniture factories, which can lock wood (including fiberboard/density board/high-density board/solid wood) very well, and is currently used to replace wood screws.
Self-tapping screws and drywall screws are often used for the connection between thin metal plates (steel plates, saw blades, etc.). When connecting, first make a threaded bottom on the connector, then screw the main wall studs to the threaded bottom of the connector. The threaded surface of the drywall screw has high hardness (HRC45), so the internal thread can be attacked from the threaded bottom hole of the connector to form a connection.
