What size t-bolt for speaker cabs?

[Adam.M]

I'm in dire need of some speaker bolts! what size do i get? M4, M5 or M6?

Anyone know if maplins sell them?

I wanna get this JCM 800 fired up... :)

RS will do them if Maplins don't (where I got my JJ valves from along with some torx screws for my Orange)

I got mine in B&Q ... I think they were M6, if there's no info with speakers or online then measure speaker bolt hole.

I got mine form B&Q, too, but they didn't do anything smaller than M6. I got home to find that the hole in the speakers as slightly too small, so I drilled them out so they'd take the M6 thread. Then I had to drill out the holes in my cab (I was putting in two new 8" drivers in my 2 x 15" cab, so I needed the 8" holes as well as the tee-nut holes!).
The B&Q in Oxford is small and rubbish :(

Thanks for all the replies! :D So m6 would be too large...

Is this what i need?

If so i'll buy a M4 and a M5 set and see which one fits best.

Neither Maplin, Machine Mart or any of the others i'd expect to stock such a thing locally do not :(

yup, that looks good to me. You might find that you need to cut the bolt down (too long, possibly), but it's really difficult to measure the exact size you need before you've got something you can stick in to measure. A junior hacksaw would work fine for this. Preferable is to measure the length you need (offer the speaker up, put a bolt/screw through and mark at the front where the screw is in line with the wood. Add a few mm on to this just to be safe :) ).
I didn't bother yet, so my 2 new speakers have 4 bolts each sticking out about 1cm from the front of the cab! Never mind, eh :)
