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.

As a screw is tightened, these washers flatten to add tension to the joint and prevent loosening from small amounts of vibration.

Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.
