Hi Sabrina,
Thank you for sharing your recent experiences of your order with us and others.
Without going into several paragraphs, the change in hex head size was the trade off we made to bring our manufacturing home to the US. We simply couldn't get it made here to the same hex size that was previously made in China.
All our descriptions and information on the product pages were updated, however, it is probably something previous owners like yourself wouldn't have read through.
If there's anything we can do to help the transition for you please let us know.
Thank you once again for taking the time out of your day to share your recent experiences, I/we really appreciate it.
Best regards
David Levine
