Where can I find 1/4 20 speaker spikes???

I looked all over for 1/4-20 spikes as an upgrade to the long, skinny ones that come with Skylan stands. Stumbled onto ones offered by Tekton which are exactly what I was looking for at a very reasonable price of $20 for a set of 8 plus $5 shipping.

Thank you for posting that turnbowm I had been looking to replace the spikes on my skylan as well.
