Flathead Screwdriver 0 products

The type of flathead screwdriver is a single straight blade, corresponding to a slotted screw, commonly with a shank of 3-8mm and a length of 75-200mm, and a chrome vanadium steel magnetized blade. Selection criteria: The width of the cutting edge must be equal to the width of the screw groove (if it is too narrow or too wide, it cannot be entered), the thickness should correspond to the depth of the groove, whether it has strong magnetism (necessary for one handed operation of small screws), and the insulation handle must have a voltage resistance certification of 1000V (necessary for electricians).
