Pittsburgh 1/4″ wobbles suck!! I broke three of them removing the top starter bolt from a Crown Vic. Two of them rounded off. The third had the head completely snap off of it. After I finished removing the starter, I threw all my HF wobbles in the trash. I purchased Kobalt. They feel 100 times better. Haven’t put them to the test yet, but I’m sure they will stand up to it for my needs.
