Sophia W. ★★★★★

Finally, steel #4-40 clinch nuts that actually stay put when pressed into thin sheet metal — no more spinning during assembly. The threads are clean and consistent right out of the pack, making each install quick and solid. Exactly what I needed for mounting brackets on enclosures.

Matthew ★★★★★

I'm replacing older steel nuts in a project and these clinch into the sheet metal far more cleanly, with no distortion. The #4-40 threads are sharp and catch evenly every time. Exactly what I needed for a permanent threaded anchor.

Brian ★★★★★

Installed these #4-40 steel self-clinching nuts into a thin aluminum panel for a project, and they set perfectly flush with zero deformation around the hole. The threading is clean and precise, accepting bolts without any binding. Exactly what I needed for secure threaded fastening in sheet metal.
