Just installed the system and was trying to mount the rear speakers on my wall. The problem arose when I found out that none the standard screws I could get my hands on would fit. I'm using metric and bought a pack of standard machine screws in sizes M5 & M6, I also tried M7. M5 was to small, M6 did go in for a few rotations but then locked up, and I looked, it was plenty more to go on the speaker. The screw only went in a couple of millimeters before it got stuck. I suspect the thread or something is off, but idk. Please help! What type of screws is right for my speaker?

Inch screw 1/4-20x 1 1/2" UNC
Thread type 20 UNC, i.e. 20 threads per inch

You need 1/4 unc thread (which is imperial) and 20mm or 3/4 inch thread length. Got mine on Ebay with a company called Kayfast.
