SMTSO-440-2ET | صواميل تثبيت ذاتية PEM #4-40 | فولاذ (200 / عبوة)

The clinching action on these #4-40 nuts was spot-on for our sheet metal panels—they seated flush with zero wobble, and the steel finish held up well under repeated tightening. Exactly what we needed for stud fastening in tight spots.

The steel construction feels solid and these #4-40 self-clinching nuts gripped tightly into the panel without any stripping. They worked perfectly for my threaded fastening project.

Just installed a batch into 0.060" sheet metal and they seated perfectly flush with zero distortion. The steel material feels sturdy, and the #4-40 threads accepted screws smoothly without any binding.
