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.

Choose these screws for their adherence to strict military standards for material and construction. Their high tensile strength means they can be used in demanding, high-stress applications.

Tighten these screws by turning them to the left; once fastened, they prevent counterclockwise-moving parts from loosening. For use in high-strength fastening applications.

Choose these metric screws for heavy duty stamping applications as well as earth-moving machinery, such as bulldozers and excavators. These screws are 10% stronger than our high-strength metric steel screws.

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.

Twice as strong as low-strength steel screws, these Grade 5 screws are suitable for fastening most machinery and equipment. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer.

Twice as strong as low-strength steel screws, these Grade 5 screws are suitable for fastening most machinery and equipment. Serrations under the head grip the surface of your material to help resist vibration. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer.
