The 8-8 stainless steel thread rolling screw for use in metal has a passivated finish and a hex washer head with a slotted drive. The 8-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic. The passivated finish enhances the natural corrosion resistance of stainless steel. The hex washer head has six flat sides that a wrench can grip to turn from the side, enabling use when there is no space above the head for a screwdriver. The nonserrated flange acts like a washer to increase the fastener's bearing surface and distribute the clamping force over a larger area, providing grip and reducing damage to mating surfaces. The slotted drive has a linear slot for use with a flat-blade driver.。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.。 。 。 。
