Shipping Details

Push nuts are designed to hold studs, nuts, and bolts in place while offering a pleasing finish to the assembly. Push nuts have an unthreaded, inward facing flange meant for quick, tool-free installation. These push nuts have no screw thread. The flange is meant for quick assembly, as no tools are needed and the nut can be pushed into place. The nut then is retained in place on the mating part. Push nuts are meant to be a permanent application unless specific tools are obtained to cut them off.

Push nuts are designed for permanent placement without the use of specific removal tools
Nickel finish for moderate corrosion protection
Simple, tool-free, push-in installation
Parts are used to secure insulation, automotive emblems, wheels on toys, electrical wires, and paneling
Push nuts are non-threaded
Parts fit 1/2-in diameter axles
