I bought the metric and SAE allen socket set from Oreilly Auto, and then the security torx set. I got tired of them rattling around in my tool box so I printed a holder for them. This can be easily remixed to hold more or less depending on how big of a set you have. All the sockets except for the 5 smallest torx are 3/8 inch drive with the 5 smallest torx being 1/4 inch drive.
