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.

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.

Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. The flange distributes pressure where the screw meets the surface, eliminating 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 metric screws are suitable for fastening most machinery and equipment. They have a serrated flange that helps prevent loosening from vibration.

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.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. A serrated flange provides mild vibration resistance.
