Does screwing into a joist weaken it?
When weight is applied to a joist, the top edge goes into compression while the bottom edge goes into tension. Improperly sized or placed holes and notches weaken the joist, make it bouncy and saggy, and provide an easy place for it to crack and fail.

They are ideal for fastening diagonally to 12” on-center (OC) joists, or in a perpendicular pattern to joists that are spaced either 12” or 16” OC.
