براغي رأس مقبس M3-0.5 X 50mm | محرك مقبس سداسي | ملولبة جزئياً | فولاذ سبائكي فئة 12.9 مطلي بالزنك (200/عبوة)

I needed long M3s for a tooling project and these 50mm ones with the partial thread gripped perfectly where I needed it. The hex socket drive made installation a breeze, and the zinc plating looks clean and durable.

Finally got around to rebuilding a jig fixture that needed these exact specs; the 12.9 alloy steel feels incredibly solid compared to the cheaper 8.8 stuff I used before. The zinc plating on every screw looked clean and uniform right out of the bag, which saved me from having to chase them for fit.

Had to order longer bolts for a tight jig setup, and these M3x50mm screws fit perfectly without any wobble. The hex socket drive made installation a breeze even in a cramped space, and the zinc plating looks uniformly applied.
