Screws for Mission Speakers

[Guitarist 28]

Hi All,
Can anyone offer and guidance/help please as I'm really drawing a blank on this one.
I've another thread relating to my Mission 770S's but I cannot progress until I can suitable fix the driver and tweeter speakers into place into the cabinet. Does anyone know what thread screws are used? I tried BA screws, M4 screws etc but nothing appears to fit.

Many thanks

A very desperate Rob!

SAE threads perhaps?

Try 6/32 UNC. If you have one as a sample, take it to Screwfix or Eurofastners and they should have them. RS components keep certain sizes of UNC and UNF.

Screwfix only sell metric bolts. A proper hardware shop or fastener supplier may still stock UNC bolts.

If you are still stuck, you may be able to screw/jam a bit of metric rod in enough to allow you to tap out the t-nut. Then fit a metric t-nut or threaded insert.

Didn't think of 6/32 UNF - thanks. I've ordered some albeit they are stainless to see if this is the size.

Regards
