3Pcs Ball End Hex Head Wrench Screwdriver Bit H8 1/4" Hex Shank 4" Long

The Hex Head Wrench Screwdriver Bit is made of S2 steel material, high hardness, and sandblasting treatment by the surface, which is stronger and more durable. The ball head is an upgraded version of the hexagonal head. When in use, the screw can be locked vertically or sideways, effectively reaching the dead angle of the screw. Strong magnetism can easily hold the screw. The ball end hex head wrench drill bit is widely used in electric screwdrivers, manual screwdrivers, electric drills, air drills, or any other electric drills with 1/4 inch hex handle, the suitable tool for repairing household appliances, precision instruments, and furniture. Notice: Because the rod is relatively long, after multiple processes of hardening and heat treatment, it is normal that the rod may be slightly bent. This kind of relatively hard steel is difficult to control in production (if it is not hardened, there will be no eccentric phenomenon).
