Review on Threading（17Mm Long） Rotating Adjustable Thumb by Andy Edwards

I was very impressed with the quality of these head bolts. The finish is near perfect with perfect threading and a good flat contact area at the end of the bolt. The spring tension is just right, the handle slides out easily but stays in place. I wish they had different length screws as I would definitely buy more. If that's what you're looking for, they're as good as they can get.
