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

These flange nuts have a black-oxide finish for mild corrosion resistance in dry environments.

For light duty applications, choose these metric-sized coupling nuts.

These metric-sized coupling nuts are Class 10 steel, so they’re about 25% stronger than medium-strength steel coupling nuts.

These metric nylon 6/6 cap nuts are chemical resistant, nonconductive, and lightweight.

These metric wing nuts provide more leverage for greater torque while tightening than knurled-head thumb nuts.

Made from 316 stainless steel, these metric wing nuts have excellent chemical resistance and can be used in saltwater environments.

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

These metric thumb nuts have good chemical resistance. The flange distributes pressure over a large area to reduce stress on your part.

Use these thumb nuts in low-clearance applications or jam one against another nut to hold it in place.

Weld these metric nuts to flat and uneven uncoated steel surfaces for a strong permanent hold.

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

Projections on the base concentrate the weld and provide room for heat to dissipate.

Weld these nuts to uncoated steel surfaces.

A smooth base on these metric nuts provides more contact with the mating surface than weld nuts with projections
