Concealed Head Standoffs
Threaded standoffs fitted into a blind hole, hidden from the front.

Keyhole-mount standoffs that slide and lock a board in place.
Hole slide lock standoffs work with a keyhole slot in the board: the board slides over the head and locks in place, allowing quick fitting and removal.
