Small Parts 0604RTU Steel Thread Rolling Screw for Metal, Zinc Plated, 82 Degree Flat Undercut Head, Star Drive, #6-32 Thread Size, 1/4" Length (Pack of 100)

The steel thread rolling screw for use in metal has a zinc plating and an 82-degree flat undercut head with a star 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 flat undercut head has a flat top with an 82-degree cone-shaped bearing surface and is undercut to a lower head height for use in shallow countersunk holes. The star drive, also called a Torx drive, has a six-pointed indentation that provides a large contact area for the driver, resisting slippage better than a Phillips or slotted drive. A star drive requires use of a Torx driver for installation and removal.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.
