back facing (hole)

Declined
I think "ザグリ穴" probably be "座ぐり穴" that is a mechanical or metallic term, and it is for screws.

¥"spotfacing hole¥" could be suited according to ¥"機械用語辞典¥". However, I would like to recommend you to see ¥"JIS 用語辞典¥" if avialble.

agree Kurt Hammond : Agree with the second URL here, but a term like countersunk or counterdrilled is maybe more natural. A google search only find 2 instance of "back facing hole"
