Basic functions of screwdriver

When repairing a mobile phone, a screwdriver is required to open the case (some mobile phone cases are concealed without a screwdriver). Most of the screws used are hexagon socket screws; different mobile phones have different specifications, generally T5, T6, T7, T8, etc. Some models are also equipped with special screws, which require a special screwdriver. In addition, you need to prepare some small flat and small torx screwdrivers.

When matching such tools, the A and B sets should be used, which almost include all mobile phone case opening tools. When opening the case, use a suitable screwdriver according to the type and specification of the fixing screws on the case. If the selection is not appropriate, the groove of the screw may be flattened, resulting in slippage.
