HFHS-0420-16 | مسامير تثبيت ذاتية PEM #4-20 | فولاذ (100/عبوة)

These clinched perfectly into the pre-drilled holes on my equipment rack, holding tight without any fuss. The steel feels solid enough for repeated assembly and disassembly.

Pressed them into some 16-gauge steel panels and they seated flush without any deformation, the knurl really bites in. A hundred per pack means I've got plenty left over for the next job, and the #4-20 threads held up fine with a stainless nut run on and off a few times.

The threads on these #4-20 studs cut cleanly into our steel brackets without any stripping. The whole pack of 100 came uniformly sized, so feeding them into the press went quick once I got the die set dialed in.
