Hi Jerry -
Check McMaster-Carr on line. An endless selection and, in my mind, hard to
beat. No minimum order, order by noon - next day delivery (at least to
upstate NY), telephone order takers who are reasonably well informed and
willing to help find what you're looking for. Yes you have to pay shipping,
but not exorbitant and probably no more than what it cost to drive around
looking. Just be sure to select and specify strap and screw - ALL -
stainless. As I recall they're available either in singles or by the box
(small number).

Subject: Re: [TowerTalk] Hose Clamps
Lots of interesting suggestions. Thanks everyone.
Here are some more observations that touch on some of the points
mentioned.
Yes, the MFJ-sourced clamps look kind of junky. The screw heads are lumpy
and of variable size as my nut driver fits over some well and will barely
fit others. I'll pick up some replacements at Home Depot -- their web site
says they have "all stainless" clamps in the right size -- and see if they
are better. I'll bring along a magnet just to be sure.
The slits in the tubing appear to be of the right width as when the clamps
get tight enough to break there's still some gap showing in the slits. I
am
lining the clamp screw housing up over the slits as mentioned in the
Hy-Gain instructions.
I'm using Noalox on the joints. This tends to lubricate the tubes so they
will slide and twist more readily even when the clamp is getting near the
breaking point. I'm sure this is making the situation worse, but since the
Noalox won't disappear when the antenna is up in the air, I still worry
that things are not tight enough.
