Which clamp to mount light to a speaker?

So a short bolt is the same as a setscrew... But a long bolt is different? I thought a set screw was just a threaded rod with no head... But now I wonder what that's called

Not quite, a bolt has a non threaded section, this gives it a better shear loading, a setscrew is threaded it's entire length. a threaded bar is just that, but if its got a non threaded section in it, then it's a stud

As previously suggested, I would go with the M10 "Thumb Screw" type. Just make sure you don't get one that's too long!

Thanks to all. Found them on amazon.

Interesting, not that I disagree with the above but the first 3 results in google images for metal bolt are setscrews and 9/13 images are of setscrews. No wonder I was confused!

Chapter and verse. Bang on.

In this case then, a picture isn't worth a thousand words.

Google doesn't' always know it all, out of interest I've just searched on google images for 'setscrew', out of the first 5 pics, 4 were of 'metal collars' containing grub screws and the other was of a box full of self tapping screws.

Time to get out the hacksaw and a file and take 10mm off?

Or a Dremel? My weapon of choice for shortening most bolts/screws & cutting thinnish metal

Of course if you're shortening anything with a thread on it, don't forget to put a nut on it above where you're cutting first - that way when you're done cutting, when you remove the nut it tends to unmess-up the thread end you've just cut
