Description
The CSP-402 set is made from heavy-duty Chrome Vanadium (Cr-V) steel, engineered to withstand the torque required to loosen “baked-in” spark plugs. These are “deep-well” sockets that allow the long porcelain body of the spark plug to fit entirely inside the tool. Each socket typically features an internal rubber insert (grommet) or magnetic assistance to grip the plug securely, ensuring it doesn’t fall out or crack during handling.
