10Pack 4 Inch Hose Clamp, Key Type Adjustable Stainless Steel 4 inch Duct Clamps, Pipe Clamp, Worm Gear Clamps, Dryer Vent Clamp, Thumb Screw Metal Clamps, Easy Turn Clamp, 4” Hose Clamps

Only con is that the handle bumps the tail as you tighten it.

Quality control could be better- I got a nasty jab from a burr on the first one. So make sure you check them and sand them where necessary. Otherwise they work as expected and stay tight

Works great.

Excellent

The clamps are good for what they are. I have not stripped one out, but there is no doubt that it could happen at some point. The main issue is that the green plastic handle you tighten the clamp with hits the tail of the clamp as you tighten the clamp. It takes two hands to tighten the clamp, One to turn the handle and the other to hold down the clamp tail. There are other clamps out there that don't have this issue, but if you are using on something that you will tighten once and forget about, these should work for you.

Feel like the keys might break if too tight.

Love these. Why didn't someone make them sooner? No more screwdrivers or square drives to adjust them. Highly recommend.

These are nicely made and easy enough to use. I use them for securing 4" flexible hose to machines on the exhaust port. Since I occasionally need to swap the hose among a couple of different machines, it's nice to have a steel band that can be used as quickly and with as few tools as possible.I have the usual type of hose clamps on other machines that don't get changed around, but these are a great addition for ones that need to be changed often.Very pleased.
