About This Product

These Thread Cutting Screws are constructed of steel, which is a magnetic material that provides strength for everyday fastening applications. They have a zinc plated finish, which provides mild corrosion resistance and a shiny finish. They also have a hex head, which has a six-sided shape that installs and removes with a standard wrench. They have a slotted hex drive, which has a single slot that is driven by a flat-bladed screwdriver. They have a 5/16"-18 thread size and a 3/4 in shank length. They have a one-piece washer, which means the washer is integrated with the fastener. Pack of 100.

About Tapping Screws

These screws form exact-fit threads as they are driven into in a material. They are good for parts that are frequently reassembled.

Cut reusable threads into sheet metal, soft metal, or plastic objects while fastening them together. These screws require a drilled or punched hole for installation.

The cutting action of the threads will not add internal stress to the material as compared to thread rolling screws, but will create shavings.
