Customer Reviews (4.8 / 5 · 5 reviews)

Mia X. ★★★★★

Finally, a #4-40 nut that actually clinches tight in thin steel without spinning during installation. The hardened steel holds up perfectly under repeated torque for mounting brackets.

Sofia ★★★★★

Installed about 50 of these on a 16-gauge steel panel and they pressed in smoothly with no slipping. That heat-treated steel holds tight even in thin sheet metal.

Benjamin K. ★★★★★

Installed a few of these into some thin sheet metal for a mounting bracket, and they seated perfectly flush without any deformation. The steel feels durable and the threads are clean, which made driving the #4-40 screw in smooth. Exactly what I needed for a secure, permanent hold.
