Product Description
Product Overview
This product is Yongjing drywall screw cross flat head self-tapping screw complying with GB14210 standard, manufactured from 1022 carbon steel material and subjected to natural color rust-proof treatment. The screw is optimally designed for quick fixation between gypsum boards and light steel keels or wooden keels. Its unique喇叭 head (flared head) and flat head shape facilitate sinking into the board surface without tearing the paper surface. The cross recess provides good driving performance, and the self-tapping threads can quickly cut into metal or wood. It is the core fastener for lightweight partition wall and ceiling installation.
Core Advantages
-
Efficient Installation and Anti-Cracking: The optimized drill point and thread design enable it to quickly cut into light steel keels, while the flared head design can be smoothly pressed into the gypsum board without easily causing board surface cracking or paper surface tearing.
-
Attractive Countersunk Effect: The flat head design combined with the flared head shape can form a good countersunk effect after tightening, facilitating subsequent plastering and decoration.
-
Good Rust-Proof Performance: The 1022 carbon steel material combined with rust-proof treatment such as phosphating can meet the construction and use requirements in indoor dry environments.
-
Economical and Practical: As a standardized building fastener, it has high cost-effectiveness and is suitable for large-scale construction.
