What is the actual range of diameters that the advertised 8" clamps will accommodate? you list 3 totally different diameter ranges in the desription?!

Rotating screw can adjust the diameter of the clamp from 7.5" to 8.5". So it is suitable for hose with a diameter of 7.5" to 8.5".

What size bolt head is on that? Try to get a socket to go with it.

its a 5/16 socket head or you can simply use a medium sized slotted head screwdriver.

Will these work for a heat shield on exhaust?

Probably, i used them to bind together my muffler and exhaust pipe. Was longer than i needed but east to cut.

Strong and very good quality.

Really good quality, strong construction, true to size and look good. I have used them round my bird feeders to stop the squirrels unclipping the feeding ports to empty the food out. They have been in use for several weeks now and do the job perfectly.

As described, working well.

I got these to mount some equipment outside on a pole, they are big enough for what I needed, installed as expected, and have been holding up outside for months now. No red flags about the weight or quality of these things, they feel decent and are working well for me so far.
