Description |
Tech Tip: Self-Drilling/Self-Tapping screws must be matched to the material thicknesses they will be fastening to work properly. Unlike fasteners selected by length and diameter, these screws are specified by point size. The self-drilling must be finished before thread tapping begins, so the drill point must be longer than the combined thicknesses of the materials. The screw will cross-thread if the two materials are at all separated when tapping begins and will cause thread stripping or drive stalling.
