No protruding screws with these clamps. Even pressure around entire circumference of hose makes a better seal.
These have to be cut off if you want to remove the hose, so not for a situation where frequent hose removal is required.
Used this with a waterhose repair kit instead of the hose clamp. Definitely more comfortable but it does allow drips. I would rather have the hose drip water than my finger drip blood!
