Buyers searching for 1 1 4 self tapping drywall screws may be using that phrase to find a particular size. The phrase itself does not establish the dimensions of this product. For the C1022A self-tapping drywall screws from Hebei Lianshi Furniture Hardware Co., Ltd., the useful questions concern material, grade, head style, finish, installation, and customization.
What material and grade are these self-tapping drywall screws?
The screws use C1022A high-grade steel and are identified as Grade 5 fasteners. Available treatments include zinc plating and phosphating. Phosphated surface colors include black, yellow, and gray.
These options give a procurement team a starting point for matching the fastener to the required finish and installation setting. The product is described for construction, interior design, architectural projects, and furniture installations.
Which head styles and installation features are available?
The available head configurations are bugle head and round head. Self-tapping threads allow the screws to penetrate the material without pre-drilling. The bugle head design sinks into drywall to create a flush, paint-ready surface.
For a drywall installation, the practical selection point is the relationship between the board, the supporting material, the thread specification, and the chosen head. A team planning a flush finished surface should specify the bugle head. A buyer seeking another screw profile should identify the round head requirement in the inquiry.
Can buyers request custom specifications or OEM supply?
Yes. OEM support includes coordination of screw head shapes and thread specifications. The screws use metric measurement, so an order inquiry should identify the required dimensions rather than assume that a search phrase represents a confirmed size.
Include the required dimensions, head style, thread details, surface treatment, color, quantity, and any packaging or brand requirements in the request. See the C1022A self-tapping drywall screws product page when preparing those details.
