براغي مجموعة سداسية ذات رأس مسطح M4 × 30 مم | فولاذ سبائكي (100/عبوة)

I needed a set screw that could handle some vibration without backing out, and the flat point on these M4s really digs in and holds tight. The hex socket drive made installation a breeze even in a cramped spot. Exactly what my project needed.

The hex socket drive was a lifesaver when I needed to tighten these in a cramped machine corner. They feel solidly made and every screw in the pack threaded cleanly.

I’ve been using these M4 flat point screws in some tight electrical panels and the hex socket drive really lets you apply torque without stripping the head. The alloy steel feels solid, not brittle like some cheaper fasteners. Solid purchase for precision work.
