I am a bit confused and looking for a part to fit the new saddle bolts used in 2020 and later Jeeps. I found this as it says this is exactly what it is for. I used a hand ratchet and an extension to make sure I didn't push too hard, but I was also able to secure the bit in the head of the bolt. The very first screw I tried to remove broke off on the first try. The beat seems out of phase so all I can say is that it's made of good material. However, I now have a seat screw stuck that I can't even get out easily. I noticed that the end of the bit was rounded and I think this contributed to him not getting a decent bite. It worked almost like a countersink and rounded off the head. Not very happy with the result.
