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.

Largest ductwork clamps!

I was working on a project and needed to clamp two large pieces of ductwork together. My local HAVAC supplier didnt even have any clamps on the shelf this size. Received these 10 inch stainless steel clamps in just a couple days and they worked perfectly.
