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 standard choice for fastening in wet and outdoor conditions. Made of 18-8 stainless steel, these screws resist corrosion from mild chemicals and water.

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 where the screw meets the surface, so you don’t need a separate washer.

When there’s not enough room to turn these screws with a wrench, slip a screwdriver into their slotted drive. They’re about half as strong as medium-strength steel screws—use them for light duty fastening applications, such as securing access panels. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer.

When a wrench won’t fit, turn these screws with a slotted screwdriver instead. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer.

Twice as strong as low-strength steel screws, these Grade 5 screws are suitable for fastening most machinery and equipment. Serrations under the head grip the surface of your material to help resist vibration. The flange distributes pressure where the screw meets the surface, so you don’t need a separate washer.
