TSellk Adjustable Stainless Steel Hose Clamp, Pipe Clamp, Self-Bringing Tools, 1/3" - 1 1/2", 40 Piece

These are so flimsy and thin, that the plastic key broke off the first time I tried to use one, and I was using the largest size clamp. Didn't even want to try the smaller ones. Returned to Amazon as a defective product. Do not advise buying if you are looking for sturdy clamps.

The ability to tighten a clamp without a screw driver makes working with the clamp a joy. I will never order a regular clamp again. The price is excellent because when you buy a single clamp the price is 4 times that of a bulk buy.
