Cheaper clamps have perforated bands with sharp edges, which tend to abrade the hose; and carbon steel screws with a stainless steel band, which causes (galvanic) corrosion, and premature clamp failure.

“AWAB” makes hose clamps with a smoother inside surface (threads are pressed, not perforated), and also have a relief cuff at the edges - both features reducing damage to the hose when clamp is fully tightened.

An excellent "AWAB" clamp - and an "el cheapo" clamp
