"How to fit a star nut
Tools for the job
-Star nut fitting tool
That made me chuckle, but I agree with the tool, as I don't have one and now have a squint and stuck star nut. Fortunately I have places to go that will have such tools so I can sort it out.
Apart from making inappropriate use of work tools, I had a chat with tame-HR-person and have a referral to occupational health.
