براغي ذات رأس سداسي M4-0.7 X 12mm | فولاذ مقاوم للصدأ 18/8 | كامل الخيوط (500 / عبوة)

These M4 hex bolts fit perfectly into my 3D printer’s extruder assembly, and the 18/8 stainless steel gives me confidence they won’t rust in the workshop. The fully threaded design held tight even under some vibration. Exactly what I needed for the price.

Needed a batch of M4-0.7 x 12mm hex heads for a jig rebuild and these worked perfectly—the 18/8 stainless feels solid and the threads were clean right out of the bag.

Finally got around to using these on a bracket I was assembling and the threads were clean, no binding at all. The 18/8 stainless feels solid and the hex heads hold up well under a socket driver.
