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.

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.

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.

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.

For strength comparable to that of Grade 9 steel and the corrosion resistance of stainless steel, choose these screws. They are work-hardened for extreme strength. The flange eliminates the need for a separate washer.

Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. Serrations under the flange provide mild vibration resistance.

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.

These steel screws are zinc plated to resist corrosion in wet environments.

The green color identifies these as grounding screws. They have a flange that provides a wide flat surface for making solid electrical connections.

These metric screws have a triangular shank that presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and copper.

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

Made from 410 stainless steel, these screws are strong, wear resistant, and mildly chemical resistant.

Stronger and more wear resistant than 18-8 and 316 stainless steel, these screws are mildly chemical resistant.

More corrosion resistant than 18-8 stainless steel screws, these have excellent resistance to chemicals and salt water.

These steel screws have corrosion-resistant finishes.

These 18-8 stainless steel screws have a hardened steel drill point to penetrate steel and are coated to increase corrosion resistance.

These screws have the strength of 410 stainless steel with added corrosion resistance.

One-third the weight of steel, aluminum screws resist corrosion in wet environments.

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

These 316 stainless steel screws have excellent resistance to chemicals and salt water.

These blue and silver ultra-corrosion-resistant coated steel screws stand up to wet environments.

Also known as Tapcons, these screws are often used to anchor parts to concrete, block, and brick. Assortments include a drill bit.
