Twice as strong as low-strength steel screws, these screws are suitable for fastening most machinery and equipment.

These metric screws help prevent counterclockwise-moving parts from loosening. Use them for medium-strength fastening.

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.

These screws come with a traceable lot number and a physical and chemical test report. Use them for high-strength fastening.

Use these general purpose 18-8 stainless steel screws for a variety of fastening applications. They have good chemical resistance.

With the strength of steel and the corrosion resistance of 18-8 stainless steel, these 17-4 PH stainless steel screws are suitable for high-strength fastening in corrosive environments.

Use these kits to connect standard-size stainless steel pipe flanges for ANSI Class 150 or 300.

Bronze screws are 30% stronger than brass screws and provide more corrosion resistance to salt water, gases, and sewage. They are nonmagnetic and electrically conductive.

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.

These Grade 5 steel screws are over 70% stronger than our stainless steel wire-lockable hex head screws. Wire these screws together through the hole in the head to get more vibration resistance than any other screw.
