براغي رأس تجويفي M4-0.7 × 25 مم | محرك تجويف سداسي | خيوط كاملة | فولاذ سبائكي فئة 8.8 مطلي بالزنك (400 / عبوة)

I needed a batch of M4 screws for a jig I was building, and these 25mm ones fit perfectly in the pre-drilled holes without any wobble. The hex socket drive took a standard Allen key easily, and the zinc plating on the heads shows no signs of scratching so far.

Zinc plating on these M4 screws held up perfectly during my jig build without any galling. The hex socket drive engaged cleanly every time with my driver.

Just finished a small precision assembly that needed exactly this length and thread pitch, and every one of the 400 seated cleanly without a single stripped head. The zinc plating has a nice even finish, and the hex socket drive grips firmly with my standard Allen key.
