Steven ★★★★★

Finally, some hardware that actually stays put in thin metal without spinning. The self-clinching action on these #4-40 nuts worked perfectly in my 0.060" aluminum bracket, no need for additional washers. Really sturdy steel threads that bite nicely with a bolt.

Chloe X. ★★★★★

Used these on a couple of thin-gauge panels I was repairing, and they seated flush without any deformation. The threads cut cleanly into the steel, so the #4-40 screws grip tight.

Owen ★★★★★

Installed a few of these in some thin steel brackets for a repair job, and they pressed in cleanly without any deformation. The #4-40 threads feel crisp and hold screws securely. Exactly what I needed for permanent threaded holes in thin sheet metal.
