براغي رأس كبس M3-0.5 × 12mm | محرك سداسي برأس زر | ملولب بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (900/عبوة)

The hex socket drive is a perfect fit for my Allen keys, and the 12.9 alloy steel feels plenty sturdy for my precision assembly work. Zero stripped heads so far, even with repeated tightening.

Bought these for a jig I was building and the 12.9 alloy steel feels seriously tough, way sturdier than the cheap ones I’ve used before. The zinc plating is smooth and even, and all 900 came threaded cleanly with no duds.

The hex socket drive grips the allen key cleanly without any slippage, even on the smaller M3 heads. Threading them into my jig setup was smooth, and the zinc plating gives a nice uniform finish. For a 900-piece box at this price, the 12.9 grade steel feels like a solid value.
