BACKGROUND
@DaBull and I have been having a discussion of Screw/bolt heads over in the Torque setting thread here. I started a new thread to focus on the various size and types of common screws/bolts used on the Grenadier. The Table will be updated over time.
There will be some variation between cars. I know earlier model Grenadiers had torx bolts along the door sill, my car has hex bolts.#

THE DIFFERENCE BETWEEN TORX AND TORX PLUS

*Commonly loosen/tighten with an Allen key or hex bit. #Commonly loosen/tighten with a socket, spanner or wrench.
Methodology: I take a selection of Torx and Torx Plus bits and work out which fits the best. When there is uncertainty, I look closely at the shape of the screw/bolt head.
