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.

Plastic square nuts are chemical resistant, nonconductive, and lightweight.
