This was an understatement for my drive adapter. The adapter had threads that I believe were M3 threaded whereas the mounting pins are what I believer are 6-32 screws. The mounting pins are not threaded well for self-tapping, so I recommend finding an old screw that used to be used for mounting optical drives into PC cases and using those to thread the holes. You can make sure you have the correct size by screwing the sacrificial screws into the old hard drive where they should fit easily before using them to cut new threads into your 2.5” drive adapter. After that, the mounting pins went into the adapter with very little effort.
For the 2012 iMac 27”, I can confirm the Blade SSD is an 8+18 pin SSDD and I believe this is a SATA drive, NOT a PCIe (NVMe) drive. I took my 2012 apart to try to add an NVMe drive with 2013 macbook adapter, and it does not fit. I didn’t have an adapter that worked so I just replaced the 3.5” HDD with a 2TB SATA 2.5” SSD and left the blade slot empty.
The SSD drives available from OWC have speeds consistent with SATA drives, so I think the benefit of replacing or filling the blade slot are pretty minimal unless you’re really trying to maximize your available storage space, in which case it’s likely better to invest in an external or network attached solution.
TL;DR 2012 iMac is an 8+18 pin setup that is likely SATA, not PCI-E so just replace the HDD with a big SATA drive.
