It has a spot for a T45 bit. Sadly, with the way it sits my size 24 combo wrench can’t get it. Im going to try to tighten it a little more after work today. But other than that there isn’t much I can do as I don’t have a tool to get into it like whatever a crow foot is lol.I believe the stem of the threaded rod of GM struts has a spot for a torx wrench. Hold the stem with the Torx or allen wrench while tightening the nut with a box wrench, or a torque wrench with a crow foot.
