Review on 💪 Enhance Your Speaker Cabinet's Stability with Parts Express 3/8 Toe Spike Set (2 Packs of 4) by Joel Payne

Good luck with that, I risked the price and tried to screw the spikes into the mounts before drilling. Well the quality control of the threads for the first 4 was poor, I couldn't install a foot by hand, only threaded the threads one turn at a time and then all the way. It's not easy to prethread at the factory, but that would result in more than 75% failure in my opinion. So don't worry, they are already packed back in the return kit.
