A straight screwdriver can ensure torque, while a cross screwdriver can distribute force more evenly.

Screwdrivers do not have round heads because round heads cannot generate torque at all. A straight screwdriver can ensure torque, while a cross screwdriver can distribute force more evenly. According to the power source, there are manual screwdrivers and electric screwdrivers; According to the type of blade, there are straight and cross shaped screwdrivers.

The high-quality screwdriver blade is made of high hardness spring steel. A good screwdriver should be hard and not easily broken, with a combination of hardness and toughness. When the screw groove wears and slips, a hammer can be used to strike the screwdriver to deepen the groove, so that the screw can be unscrewed without any damage to the screwdriver itself; Screwdrivers are often used to pry things, which requires them to have sufficient toughness and not be easily bent or broken. Overall, it is hoped that the hardness of the screwdriver head is greater than HRC60 to prevent rusting.
