They also have a slotted hex drive, which has a single slot and is driven by a flat-bladed screwdriver. They have a 5/16"-18 thread size and a 3/4 in shank length. The washer type is one-piece, 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.
