About half the strength of medium-strength steel square nuts, use these nuts in light duty fastening applications, such as securing access panels.

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 square nuts have good chemical resistance and may be mildly magnetic.

Made from 18-8 stainless steel, these metric square nuts have good chemical resistance and may be mildly magnetic.

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.

Also known as utility-pole nuts, these square nuts have a cupped shape that ensures a flush fit against curved surfaces and corners that bite into soft materials to resist loosening.

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

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

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