产品介绍
干壁螺钉的名称是从英文 Drywall Screw直接翻译过来，其在外观上的最大特征就是喇叭头造型，分双线细牙干壁螺钉和单线粗牙干壁螺钉，两者最大的不同在于前者的螺纹是双螺纹，适用于石膏板与厚度不超过0.8mm的金属龙骨之间的连接，而后者适用于石膏板与木龙骨的连接。

干壁螺钉系列是整个紧固件产品系中最为重要的大类之一。该产品主要用于各种石膏板、轻质隔墙和天花板吊顶系列的安装。

双线细牙
磷化干壁螺钉是最基本的产品系，而蓝白锌干壁螺钉是一种补充，这两者的适用范围及购买价格基本上是相同的。略有差别的是，黑磷化具有一定润滑性，攻速(攻入指定厚度钢板的速度，是一种品质考核指标)略好;而蓝白锌在防锈效果上的略胜一筹，且产品的本色浅，不易在涂料装饰后泛色。

蓝白锌和黄锌在防锈能力上几乎没有差异，仅在于使用习惯的不同或使用者的偏好。

单线粗牙
单线粗牙干壁螺钉的螺纹较宽，相应攻速也更快，同时由于攻入木材以后不会破坏木质材料本身的结构，所以比双线细牙干壁螺钉更适合木龙骨的安装。

在国外，一般施工非常注重选择合适的紧固件产品，单线粗牙干壁螺钉是作为双线细牙干壁螺钉的替代品种更适合使用在木龙骨的连接上。在国内市场，很长时间以来都是全部使用双线细牙干壁螺钉，使用习惯的更改需要一定的时间。

自钻钉
用于石膏板与厚度不超过2.3mm的金属龙骨之间的连接，有黑磷化和黄锌镀层可选。两者的适用范围及购买价格基本上是相同的。而黄锌在防锈效果上的略胜一筹，且产品的本色浅，不易在涂料装饰后泛色。

Drywall Screw is a kind of nails, its name is directly translated from the English drywall screw, in the appearance of the biggest feature is the horn head modeling, divided into double line fine tooth drywall screw and single line thick tooth drywall screw, the biggest difference between the two is that the former thread is double thread.

Product introduction
Drywall Screw name is directly translated from English drywall screw, its biggest feature in appearance is horn head modeling, divided into double wire fine tooth drywall screw and single wire coarse tooth drywall screw, the biggest difference between the two is that the former thread is double thread, suitable for the connection between gypsum board and the thickness of the metal keel is not more than 0.8mm, The latter is suitable for the connection of gypsum board and wood keel.

Drywall screw series is one of the most important categories in the whole fastener series. The product is mainly used in various gypsum board, light partition wall and ceiling ceiling series installation.

Double line fine teeth
Phosphating drywall screw is the most basic product line, and blue and white zinc drywall screw is a supplement, the scope of application and purchase price of the two are basically the same. Slightly different is that black phosphating has a certain lubricity, attack speed (into the specified thickness of steel plate speed, is a kind of quality assessment index) slightly better; And blue and white zinc on the rust effect of a little better, and the product light color, not easy in paint decoration after panning.

There is almost no difference in rust prevention ability between blue and white zinc and yellow zinc, which only lies in the difference of use habit or user preference.

Single line coarse teeth
Single wire coarse tooth drywall screw thread is wider, the corresponding attack rate is faster, and because it will not destroy the structure of the wood material itself after penetrating into the wood, so it is more suitable for the installation of wood keel than double wire fine tooth drywall screw.

In foreign countries, the general construction attaches great importance to the selection of appropriate fastener products, single line coarse tooth drywall screw is more suitable for the replacement of double line fine tooth drywall screw in the connection of wood keel. In the domestic market, double-wire fine tooth drywall screws have been used for a long time, and it takes some time to change the usage habit.

Self-drilling nail
For the connection between gypsum board and metal keel with thickness not exceeding 2.3mm, with black phosphating and yellow zinc coating optional. The scope and purchase price of both are essentially the same. And yellow zinc in the rust effect is a little better, and the color of the product is light, not easy in the paint decoration after panning.
