I removed some rod bolts on a 172 engine yesterday and used a 1/4 drive 6 sided 11mm

6 sided 11mm socket on them and lean your hand against the back of the ratchet head and tug with the other

They do round if you use a 12 point on them, especially on the windygun 😂

They’re great I’ve used them a few times on bolts that have rounded and they take them off dead easy
