Violet N. ★★★★★

These little steel nuts handled the vibration on my CNC router enclosure perfectly. The self-clinching feature made installation in thin sheet metal a breeze, and they gripped the #4-40 bolts without stripping.

Zoe P. ★★★★★

I've been using these steel #4-40 clinch nuts on aluminum brackets for a week now and they seat flush every time without deforming the surrounding material. The threads catch cleanly on the mating bolts too, which saves me from chasing them with a tap.

Samuel ★★★★★

Pressing these #4-40 nuts into a thin bracket was a breeze, and the steel clinching ring held tight without any distortion. I’ve used fifty of them across a couple of prototypes and not a single one has loosened, so the 50-pack feels like solid value for the price.
