Standard Machine Screws

12 products

These screws join metal objects together through existing tapped holes and are typically used in high-volume automotive or machinery assembly and repair because of their uniformity. They are smaller than most screws. Machine screws are identified by threading that remains the same size from the top of the screw to the bottom.

Pan Head Machine Screws

Pan head machine screws have a flat or slightly rounded top that gives a neat appearance on visible metal joints. They are used anywhere a larger screw head might get stuck or would appear out of place. These machine screws work best in materials that are thin or are not frequently accessed to avoid damage to their heads.
