Pozi Pan Thread Rolling Screw for Metal M5 x 30mm in Zinc Plated Steel

Thread rolling screws are designed to tap their own threads into pre-drilled holes in light metals and steel. The triangular shaped tip design allows the thread rolling screw to cold form the female thread into the work piece, so there is no need to pre tap the hole. These items are manufactured to DIN 7500, a standard that covers several head and drive types, including the pozi pan head in this section.
