No need to carefully line up these screws before installing—they thread in smoothly even when they’re offset up to 15°. Their pilot point guides them into a hole, and transition threads straighten them as you tighten. They’re commonly called MAThread screws.

Made to Japanese Industrial Standards, these Class 8.8 steel screws are good for fastening most machinery and equipment.

Choose these metric screws for heavy duty stamping applications as well as earth-moving machinery, such as bulldozers and excavators. These screws are 10% stronger than our high-strength metric steel screws.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water.

Made of Nitronic 60 stainless steel, these screws have a slippery surface that keeps them from sticking or binding during installation. Often used in clean rooms, they thread smoothly without coatings or lubricants that could contaminate particle-free environments.

Connect standard-sized steel and cast iron pipe flanges. These kits come with the right size and number of screws and nuts for the bolt holes in each pipe size.

Made from plastic, these screws are chemical and oil resistant, nonconductive, and lightweight.

Aluminum screws are one-third the weight of steel and have good corrosion resistance.

When a wrench won’t fit, turn these screws with a slotted screwdriver instead. Made from plastic, they’re chemical and oil resistant, nonconductive, and lightweight.

Designed for construction, these metric screws are often used to join I-beams and scaffolding. They’re Class 10.9 steel, which is at least 25% stronger than medium-strength steel.

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 distributes pressure where the screw meets the surface, eliminating the 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.

Made of brass, these screws are electrically conductive, nonmagnetic, and corrosion resistant. 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 Class 8.8 steel screws can be used to fasten most machinery and equipment. Serrations under the head grip the surface of your material to help resist vibration.

Choose these screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. Serrations under the head grip the surface of your material to help 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.

These Class 8.8 steel screws are suitable for fastening most machinery and equipment. They are over 50% stronger than stainless steel thread-locking screws. For vibration resistance, they have a thread locker bonded to the threads.

A high-strength alternative to blind rivets, use these screws when only one side of the material is accessible.

Bolt down equipment in food processing or sanitary areas while keeping out contaminants.

Cutting their own pilot hole and threads as you fasten them into material, these metric screws have a drilling tip.
