I'm looking for a cheaper way to mount the Sonos Play:3 speakers we sell which come with a 1/4 threaded mount hole. We can sell an special mount but it's expensive and I've seen in the US "hanger bolts" with a 1/4" bolt on one end and a screw thread on the other. But can't find them in the UK?

Anyone know where I could get them or another cheaper alternative?

Many thanks

Gidon

The speaker will probably have a 1/4" UNC thread. The eBay screws
are most likely to be Whitworth threads which have a different flank angle
Some will fit ok but check before buying a big stock

If the screw/bolt is in the wall... and the threaded hole is in the speaker cabinet.
Which one are you going to turn around?
Speaker or wall?

Following on from Bob's comment above, 1/4" and 3/8" Whitworth are both in common use in the entertainment industry - 1/4" Whit is camera (tripod) thread, and 3/8" Whit is European microphone stand thread (and for video cameras, portable lights and larger stills cameras too). Ironically, the Americans use a seriously odd thread for microphones*. As far as I know there is no metric thread for either mics or cameras in general use.

It's common for professional self-powered monitor speakers to have a 3/8" Whit threaded socket (sometimes two), so they can be mounted on mic stands. I've never seen one with a 1/4" socket, as it's not strong enough really.

I hesitate to ask, but if it's really 1/4" what is the socket intended for, or are these speakers really much smaller than they look?

Cheers,

E.
*5/8" 27TPI with 26TPI although I can't for the life of me remember which is for male and which for female use - basically both are nasty! This is the most common amateur thread though, largely thanks to Japanese and Taiwanese imports from the 1970s onwards.

1/4 20 is a standard thread for cameras (3/8 16 for larger kit and tripods).

You'll be able to get connecting studs/ spigots / whatever from all sorts of photographic suppliers, and if you want to go OTT have a look at such places as Hagues
