This is a screw clamp manufactured to acceptable standards of quality. It's definitely better than a lot of other clearance boxes I've seen, but nothing crazy. However, if it works well and is worth the price, I see no reason not to give it five stars. Everyone needs a C-clip or two. They are one of the most versatile tools anyone can have. You can use them to compress brake calipers, hold objects while the glue sets, stop a V-belt while removing an engine cooling fan, and more. I currently bought the 6" because it's one of the most versatile sizes, but will likely return for larger sizes in the future. When this thing is clamped down, it feels very solid and there's no play in the shaft. I am happy with it.It's worth noting that this is made in China as opposed to Taiwan where a lot of the Tekton tools are made.It's a piece of iron though.For me the finish was almost perfect.
