The inserts on the Super V bases are what looks to me  5/16" thread. Is that correct? Wish to get some fancy gliders for these speakers. They're too heavy for spikes is you're prone to move them around much.

I went to the hardware store years ago with a few of those inserts and picked up a few bolts that fit them that I use for driving them in.

I don't recall the size but do remember them being a metric size.

If you said it looks like 5/16 and Dan said it metric then the closest match is M8.

This company should have whatever you are looking for. I ordered a sample at no cost so worth checking out.

I'm not sure what the thread size is but I hot glued gliders to the spike feet so I can slide the speakers over carpet or tiles easily.

I confirmed with a 8mm metric bolt. It is 8mm.

Thanks for your help gentlemen
