Suggest you try a few different screws to find the correct size. While not all speakers have identical spikes, they are a standard screw. I have done the grinding thing and it sounds easier than it is to get a good symmetrical point. Good luck.
are spike threads standard for speakers legacy
Please tell me if the threads for speakers that can accept spikes are standard, in particular for the Legacy Focus 20/20, my dad cant find his spikes and there is no info anywhere in manual or on website, I wanted to go to Home depot and get some brass machine screws and grind them at the head, please help as I am at my dads for 2 more days and we live far apart.....he cant install these alone, thank you as always, Chad
