About Nuts, Materials, and Finishes

Low-Profile Narrow-Base Weld Nuts

A smooth base provides more contact with the mating surface than weld nuts with projections.

Low-Profile Narrow-Base Weld Nuts with Projections

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

Steel Narrow-Base Weld Nuts

These nuts can be used in channels and tight spaces where round-base weld nuts won't fit.

Metric Steel Narrow-Base Weld Nuts

Use these metric nuts in channels and tight spaces where round-base weld nuts won't fit.

Stainless Steel Narrow-Base Weld Nuts

Weld these nuts to stainless steel surfaces.

Steel Offset-Barrel Narrow-Base Weld Nuts

Weld these nuts to uncoated steel surfaces.

Stainless Steel Offset-Barrel Narrow-Base Weld Nuts

Weld these nuts to stainless steel surfaces.

Round-Base Weld Nuts

Steel Round-Base Weld Nuts

A smooth base provides more contact with the mating surface than weld nuts with projections.

Metric Steel Round-Base Weld Nuts

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

Stainless Steel Round-Base Weld Nuts

Weld these nuts to stainless steel surfaces.

Round-Base Weld Nuts with Projections

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

Weld Nuts

Square Weld Nuts

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

Steel Hex Weld Nuts

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

Metric Steel Hex Weld Nuts

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

Metric Stainless Steel Hex Weld Nuts

You can weld these metric nuts to flat and uneven uncoated stainless steel surfaces for a strong permanent hold.

Stainless Steel Hex Weld Nuts

You can weld these nuts to flat and uneven uncoated stainless steel surfaces for a strong permanent hold.

Aligning Weld Nuts

Threads float inside the retainer so you can install a bolt at a slight angle to align with off center parts.

Metric Aligning Weld Nuts

Threads float inside the retainer of these metric nuts so you can install a bolt at a slight angle to align with off center parts.
