Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer.

About half as strong as medium-strength steel screws, these screws are best for light duty fastening applications, such as securing access panels. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer.

Made of brass, these screws are electrically conductive, nonmagnetic, and corrosion resistant. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer.
