It is not that easy to perform this move. The Screwdriver or 7 Grapple Combo is a part of King Mexican Magma Drive 2.
It starts from cobra clutch and ends at screwdriver.
The command list for this combo is shown below.
The chain for it begins with move no 171 and goes till move number 179.
For performing screwdriver you dont have to perform move no 175 which is Samurai Rock and 177 which is Sol Naciente.
