Low-Profile Narrow-Base Weld Nuts with Projections
Projections concentrate the weld and provide room for heat to dissipate. Weld them to flat stainless steel surfaces for a strong permanent hold. They can be used in channels and tight spaces where round-base weld nuts won't fit.

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.
Zinc-plated steel nuts are corrosion resistant in wet environments.
