Hose Clamp Not working

[JBFG]

So I decided to buy some hose clamps to put on my SM tanks instead of cam band.
My problem is that the hose clamps are not holding on properly, the seem to slip.
I tried to tight the screw more but the clamp "skips" at that point. It seems that it doesn't want to go tighter although there is plenty of room left on the clamp to tight more.

Is this due to a defective clamp? if so can it be fixed or should I just buy new ones?

make sure they are actually on square, if they are cockeyed at all they'll move around. Also helps to put a piece of air hose over the actual screw mechanism which gives it something to grip onto as well

Thanx Tbone. I'll take it apart and put it back on again. the clamps are sheathed like this:
DGX Stainless Steel Sheathed Clamps
is that what you mean by air hose?

the sheaths like you linked tend to slip a bit. Try putting some electrical tape around the tank where the bands will go. It may give it something better to grab onto

I don't know what clamps you got but there are some cheap ones out there that strip easily. I prefer these and have never had one fail. 316 stainless is less likely to corrode.

So I took the clamp off the tank and try to screw it all the way. It definitely skip somewhere and jams. So it’s a bad clip.

Thanx for the above link!

I run a single clamp on al80's and a double one on my steel tanks. They are lower profile, cheaper and hold up better than cam bands

If the teeth on the worm drive screw are slipping you need a new clamp. You do have to be careful not to overtighten them on an all metal connection because once the teeth slip - the band side gets a bend and the teeth are increasingly likely to slip. Having something squishy under the band like a piece of hose over the clamp or thick cord for the tail snap provides a little give and makes it a little easier to get the worm clamps tight without stripping them.
