Sheet Metal Work On Cars? Airplanes? Anything?
The price, delivery and quality met all of my expectations! Any time you're fabricating with sheet metal and you need to maintain position of parts while you mark, drill, rivet or screw together, Clecoes make life so much easier. This was a great starter set assortment. I would recommend them to anyone--and when I need more, this will be my go-to supplier.

Bad job made easier
My first time using a clecko. This is a really nice beginners set. Has all that you need for normal beginners metal work. I was replacing floorboards on 72 El Camino. Bad job made easier by this kit.

These worked well and seemed to be a good value.
These are really good. Were actually more sizes than I needed but were so inexpensive it didn’t matter.

Great product.
If you have never used a set, you will wonder how you managed without them. I like this set because you get an assortment. If you had a huge job you would probably have to get more of the size you need though.

It's nice
Great little starter kit for classes taken in the aerospace industry. I've since added a 50 pack of -4 clecos, which is more than enough for the excercises that were assigned so far. My only gripe is that the pivot seems a little close to the end, making it just a little too short in grip and align the clecos and clamps before adding pressure. It's nothing that stopped me from using them, but compared to a larger and more expensive set of cleco pliers, you can see the differences.

Beginner should be rephrased to 'starter set'
These are the same clecos you can buy in bulk and in use all over the aviation industry. perfect kit for the tool box, to use with small jobs, or as a start to a big collection.
