Self-tapping screws vs self-drilling screws.

Self-tapping screws are an ideal fastener solution, as they require no pre-drilling and have a higher minimum engagement thread depth than self-drilling screws — up to 65% more depth. This provides greater holding strength and longer-term resistance to environmental factors.


Self-drilling screws are designed with a split-point tip to penetrate tough materials quickly, while the self-tapping screws use a cutting edge to create their own threads. The self-drilling screws are 4x faster to install than self-tapping screws and generate up to 40% higher holding power. With self-drilling screws no pre-drilling is necessary, they are the ideal choice for any construction or repair project.
