Alloy steel set screws dig into hard surfaces for a secure hold.

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

Use the square head to turn these screws by hand, or use a wrench when you need more torque. Also known as half dog-point set screws, they have a protruding tip that locks within a mating hole or slot to keep parts aligned.

Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. Large flat sides make these screws easy to grip with a wrench and keep them from rotating in square holes.

About half the strength and two-thirds the height of medium-strength steel square nuts, use these metric nuts in light duty, low-clearance applications.

These Grade 5 square nuts are suitable for fastening most machinery and equipment.

Two-thirds the height of typical square nuts and made of stainless steel, these metric nuts are designed for use in low-clearance applications in humid, damp, and washdown environments.

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

Unlike metal nuts, these carbon fiber square nuts won’t warp at extreme temperatures, making them ideal for heat treating and furnace fixtures.

Brass square nuts are corrosion resistant in wet environments and electrically conductive.
