In the manufacturing industry, manufacturers will use different types and styles of screwdriver heads for assembly according to different requirements for screw connection during product assembly;

Among them, the main basis for the selection of the model of the screwdriver head is torque, connection station, screw slot size, and the requirements of the screw station on length and diameter reduction, etc;

The selection of the style of the screwdriver head mainly takes into account that it is prohibited for the end user to disassemble and assemble the product without professional permission, resulting in unreliable products. Manufacturers often use screws with strange styles for connection operations, making it impossible for ordinary screwdrivers to disassemble and assemble; In this way, a matching screwdriver is required for production.
