Neither the name of the screw nor the description of the 5/16 clamp could be found anywhere. As I mentioned, I needed to get the nutsert tool with the right size, but I do not have it. As a result, I now have to go to the hardware store to get Nice item. I am using it in a race car to hold a cable attached to a parachute.
Highly recommended.
The quality of these is good, clean, and easy to use.
This thread has 7 threads. The machining is not perfect, I have had to use a file or carbide burr or drill or cutting wheel to slightly modify a few of them, but it is not a major issue. It might be worth your time to check out Summit Racing or Jegs, both of which had a cheaper price than Amazon and ship very quickly.
Their fit and finish are a little sloppy, but they do the job.
Those are the channels that I used to install transmission lines on my Trans Am. My only attempt at drilling a hole in the frame was to drill a hole in it. Screwed them in after tapping them to the thread. This is a very tidy looking site.
I must now find nuts that will I think I will go to the hardware store, but it is not worth the trip back.
