Just wanted to let you know. This is where I went and the prices are WAY cheaper than what you will see at online rc shops. You can get like 50 for the price of 5. Plus they have any screw you would ever need. I spent like 20$ and have a bunch of spares left over. Plus their screw are a good quality. I got the black ones. They may not ook as bling but they are way harder than stainless.
