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.

Square weld nuts have more weld points than hex weld nuts for a stronger hold. Use them on flat surfaces.

Stainless steel snap-in nuts have excellent corrosion resistance in most environments.

Difficult to grasp with standard hand tools, these metric nuts have sloped sides to reduce the risk of unwanted removal.
