Review on 🔧 ROCKETSOCKET 18 Piece ¼” Drive Bolt Lug Nut Extractor Socket Tool Set – RAZORGRIP Technology for Easy Removal of Damaged, Frozen, Rusted, Rounded-Off Bolts, Nuts & Screws – Made in USA Steel by Jason Pruett

When you need round bolts and the head size is less than 10mm you need this set. I tried removing the 8mm head gear head bolts with a cheaper 8mm head set and it took off 12 out of 14 but 2 were rustier than the others and even more rounded. When I got this set I was using a 7.5mm head and it stuck and the other two came out right away. If you are dealing with smaller sizes then you really do need to be in between sizes as there is very little material to begin with. It's expensive and I didn't want to spend the money, but not having to drill a hardened screw into the aluminum gear case was worth every penny.
