3/8"-16 Plain Steel Retainer Weld Nuts - Pack of 50 for Automotive, Metal Fabrication & DIY Projects

Retainer weld nuts, also referred to as bridge weld or floating cage nuts, are nuts in a "cage" that can be welded to an installation material. The nut inside the cage is free-moving to allow for fasteners that are slightly mis-aligned to still install properly. This can help compensate for building inconsistencies.
