These metric screws are suitable for fastening most machinery and equipment. They have a serrated flange that helps prevent loosening from vibration.

Choose these metric screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are about 10% stronger than medium-strength steel screws. Their serrated flange helps to resist vibration.

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.

Serrations under the head grip the material's surface for mild vibration resistance. The flange distributes pressure across the material's surface, eliminating the need for a washer.

Serrations under the head act as a brake to prevent over tightening and damaging threads.
