Sump Drain Key Square Socket Tool

Chrome vanadium steel hardened and tempered. Square drain plug key for the oil sump plug. The square hole in the sump plug requires an uncommon tool - this is it! Clearance is tight in this area, so this tool allows you to remove the sump plug using a spanner, where otherwise a socket wrench would be an awkward (or impossible) fit.

You will need one of these if you're doing an oil change.
