Made to Japanese Industrial Standards, these Class 10.9 steel 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 eliminates the need for a washer.

Comparable in strength to Grade 9 screws, these are about 20% stronger than high-strength steel screws and often used in heavy duty applications, such as stamping and earth-moving equipment. The flange eliminates the need for a washer.

These screws are chemical and oil resistant, nonconductive, and lightweight. The flange eliminates the need for a washer, distributing pressure where the screw meets the surface.

These screws have a flange that's at least 10% larger than a standard flange for more gripping power. Serrations under the head provide mild vibration resistance.
