براغي M3 × 12 ملم رأس مسطحة مقبس | فولاذ سبائكي (1000 / عبوة)

The hex socket drive made installing these into a tight bracket setup so much easier than using a standard driver. They threaded cleanly into the alloy steel base without any stripping. Exactly what I needed for this small hardware project.

The flat points seated perfectly against the angled surface I was securing, and the alloy steel feels tough enough for repeated adjustments. A thousand pieces in the bag means I won't need to reorder for a while.

These set screws are perfect for my 3D printer adjustments. The hex socket drive lets me torque them firmly in tight spots without stripping. All 1000 pieces were consistent and cleanly threaded.
