Firstly the quality of this part is just superb, made in Taiwan but the materials and workmanship are as expected, no complaints. My problem is the thread size. Mine came with an odd 1/2-12 thread pitch not available anywhere else but apparently with this tool. So if you're planning on buying a T-Nut or nut other than a loop nut that comes with the kit, you're SOL. Inventing a new thread pitch just for this tool makes no sense in my opinion. At first I thought it was metric, but when it turned out to be 9/16" spacing with a 1/2" hole diameter, I was very disappointed. Much luck.
