High-Low Screws

High-low screws—or hi lo screws, as they are often called—have double-lead threads (where two grooves have been cut around the shaft). This kind of screw includes a high thread and a low thread. The unique qualities of hi-lo thread specifications help minimize the amount of material displaced as the screw is driven into the material, while also serving to create a stronger grip than would otherwise be possible.

Here you can explore the wide range of high-low self-tapping screws available now through Mutual Screw & Supply. Our inventory features flat head, hex washer head, pan head, and wafer head screws. Feel free to contact us with any questions about our high-low thread screws.
