When To Use Thread Forming And Thread Cutting Self Tapping Screws?

Thread Forming Self Tapping Screws do not remove the material to make thread hence ideal for non- brittle plastics. They also allow many cycles of assembly and disassembly without compromising the fastening. Thread cutting on the other hand is ideal for brittle plastic as it has lower tensile pullout and lower hoop stress. Tappex.co.uk is now sells online wholesale materials.
