These screw clamps meet my expectations and I am very happy with them. They are excellent for welding and other high pressure applications. QUALITY FINISH: The nickel plating on these clips is great and they seem to resist rust very well. Comfortable Handles: The handles are comfortable and won't slip off as easily as other inferior hand tools. clamping performance. The clamps themselves work very well. The pivoting pads (point of contact) are designed so that you can apply them without worrying that they won't "set right". Also, the swivel is tight and you don't have to worry about the clamps tipping to relieve pressure. All in all a very well made and precise instrument. Check Your Dimensions: As mentioned before, you need to check the working dimensions of the specific clamp model you are using. They work particularly well for 2.4"/60mm or less (slightly larger than the 2.6" unclamped spacing). Final Thoughts: These clamps are of a higher quality than many other clamps I have seen. They work very well and I recommend them.
