Self taping could mean quite a variety of products that are out there.
Once you figure out what sort of fastener goes into those Husqvarna brass inserts please post back. Is it a machine screw like 5mm diameter and some logical threads per mm with thread angle of common machine screw or more the sheet metal self forming type thread. My guess is they are the machine screw as they say can be used in magnesium.
