The Ko-ken AG112H is an 18-piece 1/2″ square-drive hand impact (attack) driver set, designed for loosening stubborn, seized, or rusted screws and bolts by converting hammer impact into high torque.
The driver features a hardened cam section for wear resistance and a lower-hardness impact head intended to reduce cracking from hammer blows.
Suitable for: automotive repair, machinery maintenance, industrial equipment, construction, and general mechanical work where conventional screwdrivers cannot loosen seized fasteners.
