Replacement Axle for Delrin Severe

Hi guys,
The axle for my delrin severe appears to be slightly bent (it wont screw in smoothly). I was looking to buy another axle for it, but I am not sure where to buy one of what size it is. Can anyone help?

I think you’re looking for the 12mm axles. They seem to be out of stock, but look at this: http://shop.yoyoexpert.com/product/197/YoYoFactory-Axles
