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

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....
