Unbranded 1/4 in. Zinc-Plated Open-Acorn Push Nut

These push nuts have no screw thread but have an inward facing flange which retains the nut on the mating part. The flange allows for quick assembly as no tools are needed and the nut can be pushed into place. Push nuts are meant to be a permanent application. Acorn style partially or completely covers exposed threads depending on type used.
