About Hex Head Screws and Bolts

High-Strength Metric Class 10.9
Steel Flanged Hex Head Screws

These metric screws are at least 25% stronger than medium-strength steel screws. Use them in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. The flange distributes pressure where the screw meets the surface, so there's no need for a washer.

JIS High-Strength Steel Flanged Hex Head Screws

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.

Medium-Strength Metric Class 8.8
Steel Flanged Hex Head Screws

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.

Stainless Steel Flanged Hex Head Screws

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.

Medium-Strength Metric Class 8.8 Steel
Serrated-Flange Hex Head Screws

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

High-Strength Metric Steel
Serrated-Flange Hex Head Screws

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.

Super-Corrosion-Resistant 316 Stainless
Steel Serrated-Flange Hex Head Screws

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.

18-8 Stainless Steel Serrated-Flange Hex Head Screws

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