Review on 4 Pack 3" Stainless Steel Hose Clamps - 75-90Mm Adjustable Worm Gear Duct Clamp by Cory Miles

Over all they seam to be a sturdy clamp . It has an odd size screw (6MM) in my years of servicing commercial laundry equipment most clamps of this size are either 7mm or 1/4 inch. They are an 8mm band with which is what I needed. I put a magnet to the band, screw, and housing and the whole clamp was non-magnetic which would indicate a good quality stainless steel. The inside of the bands could be finished better. they are a little rough and the "teeth" of the band will dig into the hose .
