The following is an introduction to high - strength coarse - thread drywall screws:

Features
• High Strength: Made of high - quality carbon steel materials and through heat treatment processes, the surface hardness can reach HV560 - 750, and the core hardness is between HV240 - 450. It can withstand large pulling and torsional forces, and is not easy to deform or break.
• Coarse - Thread Design: The thread pitch is larger than that of ordinary drywall screws. When screwed in, it can penetrate deeper into the material, forming a stronger connection, providing greater friction and fastening force, making the fixing effect more reliable. Moreover, the driving - in speed is fast, saving construction time.
• Self - Tapping Performance: The head is in a sharp flared shape. There is no need to pre - drill holes, and it can be directly driven into materials such as wood, gypsum board, and thin metal sheets, and complete the tapping and fastening process by itself, improving construction efficiency.
• Surface Treatments: Common surface treatments include black phosphating and galvanizing. The black phosphating treatment forms a black phosphating film on the surface of the drywall screw, which has good rust - prevention and corrosion - resistance capabilities and also has a certain lubricity, facilitating screwing in. The galvanizing treatment can form a zinc layer on the surface of the drywall screw, effectively preventing rust and extending the service life.

Specification Sizes
• Diameter: There are various specifications, and common ones are 3.5mm, 4.2mm, 4.8mm, 5.5mm, etc.
• Length: Generally between 16mm and 70mm, such as 16mm, 25mm, 35mm, 55mm, 70mm, etc., which can be selected according to different application scenarios and material thicknesses.

Application Fields
• Building Decoration: Mainly used for connecting gypsum boards to wooden or light - steel keels, and also for the installation of light - weight partition walls and ceiling suspensions. It can also be used in the construction of wooden - structure houses, such as the fixation of wall panels and roof panels.
• Furniture Manufacturing: In furniture manufacturing, it is used for the connection and fixation of plates. For example, in the assembly of wardrobes, cabinets, bookshelves, etc., it can make the connection of plates more firm and ensure the structural stability of furniture.
• Other Fields: It can also be applied to the connection and fixation of thin metal sheets and composite materials, such as the fixation of thin plates in simple buildings, the installation of vehicle interior panels, and the assembly of electrical equipment cabinets.
