Small Parts M325D7500C Steel Thread Rolling Screw for Metal, Zinc Plated, Pan Head, Pozi Drive, Metric, M3-0.5 Thread Size, 25 mm Length (Pack of 100)

The steel thread rolling screw for use in metal has a zinc plating and a pan head with a pozi drive. Steel is often used in applications where strength is the primary consideration. The zinc plating offers corrosion resistance and has a reflective appearance. The pan head has a flat top and short vertical sides with a rounded top edge. The pozi drive is similar to a Phillips drive but with straight sides and additional markings on the Phillips cross that reduce the likelihood of the pozi drive driver slipping out and increase the amount of rotating force that can be used.Thread cutting and thread rolling screws, two types of self-tapping screws, are threaded fasteners that create a mating thread in the wall of a hole. The two screws differ from each other in the way that they create the threads. Thread cutting screws cut the wall of the hole to create the thread, creating material chips that need to be cleared away from the hole to prevent clogging. Thread rolling screws, also called thread forming screws, do not remove material but instead press against the wall of the hole to displace the material and form the threads.
