Review on πŸ”Œ Efficient Power Transmission: European Standard Anodized Aluminum Extrusion Products by Josue Porter

Revainrating 4 out of 5

The enlarged holes are perfect for the m5 helix coil

These are decent profiles. The price appealed to me, but there was one fixable drawback for my application, the end holes were too big. If you don't plan on using the hardware in the hole of these profiles, you'll be happy. As many others have said, the holes end up being too big for threading m5 hardware, which is the standard. The holes are approximately 5.2mm, which is the size of the drill that comes with a cheap m5 helix coil. Cut a hole for the spiral coil, screw it in and now you have a perfectly usable m5 thread.
