Coarse Thread Drywall Screw

Characteristics and applications of Jiaxing Chishing® coarse thread drywall screw

The biggest feature of drywall screw in appearance is the shape of horn head,which is divided into double thread fine thread drywall screws and single thread coarse thread drywall screw. The biggest difference between the two is that the thread of the former is double thread,which is applicable to the connection between gypsum board and metal keel with thickness not exceeding 0.8mm,while the latter is applicable to the connection between gypsum board and wood keel.

Coarse thread drywall screw series is one of the most important categories in the whole fastener product line.Coarse thread drywall screws are mainly used for the installation of various gypsum boards, light partition walls and ceiling ceiling series.

Carbonized coarse thread drywall screw is the most basic product line,and blue white zinc coarse thread drywall screw is a supplement.The application scope and purchase price of the two are basically the same.The slight difference is that the black photostatting has certain lubricity, and the attack speed (the speed of entering the specified thickness steel plate,which is a quality assessment index) is slightly better;Blue and white zinc is slightly better in rust prevention effect,and the natural color of the product is light,which is not easy to be colored after coating decoration.

There is almost no difference between blue white zinc and yellow zinc in rust prevention ability,only due to different usage habits or user preferences.
