CLA-440-2 | مثبت ذاتي التثبيت PEM #4-40 | فولاذ (100 / عبوة)

Pressed these into a 16-gauge sheet and they seated perfectly flush, no deformation on the back side. The steel threads held a #4-40 screw securely during a test assembly. Exactly what I needed for mounting brackets in thin metal panels.

Installed a few of these steel #4-40 fasteners into some thin sheet metal and they seated perfectly flush without any deformation. The self-clinching design held tight on the first try—no need for additional hardware. Very pleased with how solid they feel.

Finally got these #4-40 fasteners in and they seated perfectly into the aluminum panel on my first try. The steel feels solid and the threading grabbed cleanly without any cross-threading issues.
