What do you need to pay attention to when installing the handle?

Drilling holes in the handle installation material, the first reference size of the aperture should be determined according to the size of the mounting hole on the handle, if the opening hole is too large, the handle will not be firmly installed, and it will be difficult to screw in the small installation screw. The names of each part of the drilled hole are also different, the starting part is called the hole mouth, the side part is called the hole wall, and the bottom is called the bottom of the hole. The size of the aperture at the opening and the bottom of the hole is generally different, respectively called the opening diameter and the final hole diameter.

The hole depth must be taken into account the thickness of the plate at the installation position, and the hole depth can not be punched according to the unified hole depth, which will lead to problems at the stress point of the plate at the installation, and eventually lead to the pull falling off. The treatment methods on wood and plastic sheets absolutely need to be distinguished.
