Steel Hex Weld Nuts
Weld these nuts to flat and uneven uncoated steel surfaces for a strong permanent hold. A collar pilot assists alignment and prevents welding spatter from getting into threads.
All nuts meet ASME B1.1 and comply with specifications for dimensional standards.

Steel Round-Base Weld Nuts
A smooth base provides more contact with the mating surface than weld nuts with projections. The base also acts as a flange to distribute the load. A long barrel ensures secure thread engagement.

Aligning Weld Nuts
Threads float inside the retainer so you can install a bolt at a slight angle to align with off-center parts. Weld these nuts to materials for a strong permanent hold or punch holes in the flanges and secure them with rivets.
Weld zinc-plated steel nuts with aluminum retainer to aluminum parts.

Screw-Mount Nuts
These nuts have three mounting holes to accept screws and rivets. Insert the barrel through a hole or fasten the base with the barrel facing upward for use with thin materials. The longer the barrel, the more thread engagement with your screw.
