FHS-0420-14 | مسامير ذاتية الكبس من PEM #4-20 | ستانلس ستيل 18-8 (100/عبوة)

I’ve been using these #4-20 studs to attach brackets to sheet metal enclosures, and they press in cleanly without any deformation. The threads are crisp and the stainless steel hasn’t shown any rust after a few weeks in a humid shop.

The 18-8 stainless steel finish feels solid and should hold up well in my shop, and the threads cut cleanly into the sheet metal without any galling. I went through half the bag on a jig build and every single one seated flush like it should.

The threads cut cleanly into the aluminum panels I’m working with, and the 18-8 stainless finish hasn’t shown any rust after a week in a damp shop. Only nitpick is that the bag doesn’t reseal, so I had to transfer the extra studs myself.
