The following is an introduction to high-strength coarse-thread drywall screws:
Key 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, 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, effectively preventing rust and extending the service life.
Specification Sizes
Diameter Specifications
Available in various specifications. Common options include: 3.5mm, 4.2mm, 4.8mm, 5.5mm, etc.
Length Specifications
Generally ranges between 16mm and 70mm, such as: 16mm, 25mm, 35mm, 55mm, 70mm, etc. (Selectable 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.
Frequently Asked Questions (FAQ)
Q:
What are the main advantages of high-strength coarse-thread drywall screws?
These screws feature high surface and core hardness, allowing them to withstand significant pulling and torsional forces without breaking. The coarse-thread design provides greater friction and fastening force for a faster, more secure installation.
Q:
Do I need to pre-drill holes before driving these screws?
No, you do not need to pre-drill holes. The sharp flared head and self-tapping performance allow the screws to be driven directly into wood, gypsum boards, and thin metal sheets.
Q:
What surface treatments are available for these drywall screws?
We offer various surface treatments including black phosphating (for rust prevention and lubrication), galvanizing (ZP), hot-dip galvanizing, high-definition, and Dacromet, depending on your corrosion resistance requirements.
Q:
What are the standard sizes and lengths for these screws?
Common diameters include 3.5mm, 4.2mm, 4.8mm, and 5.5mm. Lengths generally range between 16mm and 70mm (such as 16mm, 25mm, 35mm, 55mm, and 70mm) to match different material thicknesses.
Q:
What is the Minimum Order Quantity (MOQ) and production capacity?
The minimum order quantity is 100 pieces per order, and our monthly supply capacity is approximately 10,000 pieces.
Q:
What standards and certifications do these screws comply with?
Our products are manufactured according to DIN, GB, UNC, BSW, and JIS standards, and are certified under ISO9001, ISO14001, ISO45001, and SGS.
