How to use the screwdriver correctly? 

Generally, the screw needs to be used with a screwdriver, which is why there is a screw groove type. How to use the screwdriver correctly? For the Phillips type screws, select a “cross” type screwdrivers that meets the screw specifications. During the operation, the screwdrivers should be straightened, the head of the screwdrivers should be close to the notch of the screw head, and the torque should be moderate when the screw is tightened. It should be noted that the damaged screwdrivers cannot be used, because the screwdrivers will be easy. Wear the head of the screw.

What should I do if I encounter a screw skew during the assembly process? First of all, the reason for the embarrassment may be that the screwdriver is not vertical when it is dropped; the screwdriver is shaken to cause the screw to be skewed; or the mounting surface is skewed. How to avoid these situations? First, the screw assembly should be perpendicular to the surface of the object being locked, or the horizontal fixing tool can be added to make the locking surface level.

In fact, sometimes the screw is not the reason why the screw is not assembled. It may also be that the screwdriver is not used correctly. The requirements of screw quality for the Shi Shi Tong screw factory are very strict. Please contact the Shi Shi Tong screw factory if you need custom manufacturing screws: annie.li@szsst88.com
