So, I just happen to have a set of vernier calipers, 3 Apple adaptors, and a Samsung adaptor to hand.
Apple A1299 & A1399 (pictured) have grab dimples & the earth pins measure 4.03 x 8.06mm & 4.06 x 8.06mm.
The A1718 MBP USB-C adaptor is 4.02 x 8.04mm.
The Samsung USB-C adaptor is 4.02 x 8mm.
Might be a high friction surface finish on the metal pin on the Apple products? I could just imagine Sir Jonny giving it that level of detail.
@StuInNorway @guardeddon they do!
@bloor @guardeddon That seems odd, most of these are double insulated, and most are glued shut too. No metal to earth really.

As I wrote, likely Jonny & Steve attention to detail reasons 🤷🏻♂️
I doubt the 0.02mm, here & there, makes a difference. The socket usually employs a simple folded metal jaw clasp.
@guardeddon @bloor Do they really use a metal earth pin on that ? Surely the adapter is double insulated and they could use a cheaper plastic pin ? (Also easier to sand down if stiff)
