F. install the gusset plate and gusset box, make them parallel to the lock and match the lock tongue.

F。 安装扣板及扣盒，对齐锁体，应使锁舌与之配合顺畅，拧紧所有螺钉。

H. Screw down the screws, install the gusset plate and gusset box, make them parallel to the lock and match the lock tongue.

H。 拧紧螺钉，安装扣板及扣盒，对齐锁体，应使锁舌与之配合顺畅，拧紧螺钉。

For example, every rivet or screw in the junction are a lot of pressure on the media, and this may lead to material deformation or damage, the hole in the material may also lead to leakage or loose, together with mechanical fasteners are visible position, to have it hidden, or to identify the surface rendering, we will encounter some difficulties.

比如，每个铆钉或螺钉在连接处都对介质有很大压力，也许能导致材料变形或损坏，在材料上打孔也可能导致泄漏或松脱，再加上，机械扣件都是在显眼的位置，要把它掩藏或给标识进行表面绘制时就会遇到一些困难。
