Put it at the scare beat after your tension build, starting with a danger alarm sound effect to warn viewers, then this clip, then an fnaf jumpscare scream for a second, bigger hit in the following scene.

This is an 11-second jumpscare sound effect built as an alternative version of the new scare from Five Nights at Hanwil's 2, credited to CinemaHanwil. It lands as startling and tense, made to trigger that instant flinch and nervous laugh you get when a quiet horror moment suddenly turns threatening.
