Small Parts 1110RSWS #10-32 Steel Thread Rolling Screw, Zinc Plated, Serrated Hex Washer Head, Slotted Drive, 5/8" Length (Pack of 100) for Metal Fabrication and Assembly

Product Description

The steel thread rolling screw for use in metal has a zinc plating and a serrated hex washer head with a slotted 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 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 serrated flange acts like a washer to increase the fastener's bearing surface and distribute the clamping force over a larger area, providing a grip that resists loosening. 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.
