مسامير M4 × 55 مم | نحاس (100 / عبوة)

Finally found some decent-length M4 studs that are actually solid brass, not just plated. The 55mm length gave me just enough thread for my jig build without bottoming out. Pack of 100 should last me a while.

The threads are clean and consistent across all 100 pieces, which saved me a ton of time on a batch assembly job. The 55mm length gave me plenty of grip for the brass nuts I paired them with, and the finish feels solid for general fastening work.

These brass studs threaded perfectly into my M4 nuts without any binding, and the 55mm length gave me just enough grip for a medium-thickness bracket mount. The corrosion resistance is a nice bonus for outdoor use.
