Product Description

Drywall Screws Application

Drywall screws (self tapping screws) are the main fasteners used to fix gypsum boards in indoor decoration, especially suitable for ceiling and partition construction.During installation, it is necessary to use fine thread dry wall nails (suitable for light steel keel) or coarse thread drywall screws (suitable for wooden keel), with a length of usually 25-35mm (single-layer board) or 38-50mm (double-layer board).During construction, screws should be evenly inserted into the keel at a spacing of 15-20cm, and the screw's head should be slightly recessed (1-2mm below the board surface) for subsequent coating coverage.For the ceiling, it is recommended to increase the spacing to 10-15cm to enhance load-bearing capacity; A distance of 10-15cm should be reserved at the edge of the partition wall to avoid cracking.Normal use of black phosphating drywall nails can be replaced with galvanized or stainless steel materials in damp areas such as kitchens and bathrooms to ensure long-term stability. 

Drywall Screws Advantage

Advantages:

Easy installation and high construction efficiency

Drywall screws are self tapping designs that do not require pre drilling and can directly penetrate gypsum boards and keels (wood/light steel). If carbon steel or 410 stainless steel is used as the material, an electric screwdriver can be used to quickly fix them in bulk, improving construction efficiency.

Cost economy

Drywall screws are inexpensive and have uniform specifications, making them suitable for large-scale construction and reducing material and labor costs.

High strength fixation

The thread design (coarse/fine) of drywall screws is suitable for different keel materials, with strong grip to avoid loosening or sagging of gypsum boards.Dry wall screws, also known as horn screws, have a "horn shaped" design that disperses pressure and reduces the risk of surface cracking on gypsum boards.
