Tool preparation: According to the specifications of the screws (M3 or M4), choose the appropriate size of Phillips screwdriver to ensure that the bit and the cross slot of the screws closely fit to avoid slipping in the process of screwing.
Preparation before installation: Before installation, clean the surface of the parts to be fixed, remove dust, oil and other impurities to ensure that the screws can closely fit the surface of the parts to achieve the best fastening effect. At the same time, according to the length of the screws and the material of the parts to be fixed, to determine whether it is necessary to pre-drill holes. For harder materials (e.g. metal) or longer screws, it is recommended that holes be drilled first using a suitable drill bit to prevent the material from cracking when the screws are screwed in.
Installation process: Align the screws with the pre-drilled holes (if any) or directly to the position where they need to be fastened, and then use a Phillips screwdriver to screw the screws in slowly. To begin, gently rotate the screwdriver to initially get the screws into the holes, making sure that the screws are perpendicular to the mounting surface and avoiding tilting. Next, gradually increase the force to tighten the screw, but do not over-exert yourself to avoid damaging the screw or the part being secured. For longer screws, if you feel it is difficult to screw in, you can pause appropriately to check whether the screw is perpendicular and whether there are any foreign objects obstructing the hole, and then continue to screw in until the screw is completely tightened and is either flush with the surface of the component or slightly below the surface (according to the actual needs).
Removal steps: If it is necessary to remove the screw, again use a suitable Phillips screwdriver, insert the head of the screwdriver into the Phillips slot of the screw, and then rotate the screwdriver counterclockwise to gradually loosen the screw. During the loosening process, keep the screwdriver perpendicular to the screw to prevent slipping. If the screws are tight because they have not been disassembled for a long time, you can drip a small amount of lubricant and wait for a few moments before trying to unscrew them, which will reduce the resistance during disassembly and avoid damaging the screws and mounting parts.
