FE-440-MD | مسامير PEM ذاتية التثبيت #4-40 | فولاذ (100 / عبوة)

Pressing these into 0.06" sheet metal was almost too easy—they seated flush with zero deformation on the back side. The steel feels plenty tough for a general assembly jig I'm building, and the #4-40 threads cleaned up nicely with a tap. Hundred pieces in the bag means I won't run out mid-project.

The clinch action is solid—pressed them into 1.5mm steel plates and they seated flush without any distortion. Threads are clean and consistent across all 100 pieces, which made assembly go much faster than I expected.

Worked perfectly for mounting a thin aluminum panel on my project. The self-clinching feature made installation quick and I didn't need access to the back side.
