Thread forming and cutting screws form or cut their own threads in preformed holes, saving the cost of pre-tapped holes or inserts.  They can be installed in metal or non-metal materials.  There are many different styles of thread forms, all with a specific type of application.  All standard head styles and drive systems may be utilized.  Zip Fastener Products will help you determine which thread style fits your application.
