The worm gear clamps are good ones....if you find GOOD ones. I threw away an assortment of them that I pickup up long ago at harbor freight and some other places.
Last week I went to Advance Auto and ask the lady in Commerical if she still sold the "good ones" to the garages out of the big boxes. I think I paid .79 cent a piece for some good thick ones.
If you buy them prepackaged off the rack your wasting your money.
There are good worm clamps out there..... .but hey, I'm almost ready to go back to the "wire" clamps. Never have to tighten them up. Had a "cold" water leak on a manifold that I couldn't stop until I put a wire clamp on it so it could "breath".

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
