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 over the surface, eliminating the need for a washer.

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.

Choose these metric screws for fastening most machinery and equipment. With a flange distributing pressure where the screw meets the surface, there is no need for a separate washer.

Made from 18-8 stainless steel, these screws have good chemical resistance. A flange under the head distributes pressure over the surface, eliminating the need for a washer.

For strength comparable to that of Grade 9 steel and the corrosion resistance of stainless steel, choose these screws. They are work-hardened for extreme strength. The flange eliminates the need for a separate washer.

Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. Serrations under the flange provide mild vibration resistance.

About 20% stronger than medium-strength steel screws, these Grade 8 steel screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. Serrations under the flange provide mild vibration resistance.

Made from 18-8 stainless steel, these screws have good chemical resistance. Their flange is serrated to help prevent loosening from vibration.
