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

My Dali's spikes are a metric #8. I cut the heads off of some bolts purchased at Home Depot and used thick rubber washers with a hole in the center to create rubber feet instead of spikes to use on hard wood floors. They work as well as spikes without damaging the floor. I don't know if other manufacturers use the same thread size though.

I had the signature iii and they had 7/16 x 20 thread.

thanks guys, it does seem smaller than 7/16.....more like 1/4 inch..anyone have any other thoughts to add?

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.

Seems like 1/4 inch is right. You might want to get nuts as well so you can lock them from turning once they are set.

Chad,

Another idea to try....I removed the rails and spikes from my 20/20's altogether and have the Focus 20/20's on a 4 Black Diamond Racing Super Jumbo Pucks per side. This makes a hell of a difference over any spike that I tried with the Foci....
