براغي رأس مقبس M12-1.75 × 30 مم | رأس مسطح محرك سداسي المقبس | كاملة الخيوط | سبيكة فولاذ كلاس 12.9 مطلية بالزنك (100/عبوة)

The flat head sits flush perfectly in my jig, and the hex socket drive grips tight without stripping. These screws feel rock-solid, exactly what I needed for a precision assembly project.

Fine threads and the 12.9 alloy steel give these screws a solid, precision feel—much better than the cheaper stuff I've used before. The zinc plating seems durable, and they threaded smoothly into my fixture without binding.

I needed these for a jig I was building, and the hex socket drive made installation much easier than a standard bolt head. The zinc plating looks clean and seems like it'll hold up well on the shop floor. Only minor thing is the threads could be a touch cleaner out of the package.
