Generally, when we need to install two accessories, we usually need screws to tighten them. It may be a machine screw or it may be a steel self-tapping screw. Then how to install steel self tapping screw?
Some people say that there is no need to punch holes in the installed parts in advance when installing steel self tapping screws, just take the screws and attack them directly. Some people also say that it is necessary to punch holes in the installed parts in advance so that it will be better when fastening. In fact, both ways can be done.
If the fitting is not punched in advance, then the steel self tapping screw may appear during the installation and be a little crooked when tapped, or the electric screwdriver may not be used, so little effort will be spent in the screw and it cannot be screwed in. If holes are punched in the installed parts in advance, we can tighten the parts quickly when screws are used for fastening. It does not require so much effort and time, which can improve our work efficiency.
