براغي رأس كبسولة M6-1 X 140mm | محرك سداسي داخلي | ملولبة جزئياً | فولاذ سبائكي فئة 12.9 مطلي بالزنك (50 / عبوة)

The hex socket drive gives a solid grip without stripping, and the zinc plating looks clean and durable. I used them for a jig assembly and all 50 fit perfectly without any burrs or defects.

The 140mm length was exactly what I needed for a jig assembly, and the zinc plating looks clean and uniform across all 50 pieces. Threading went smoothly into my fixtures without any binding, which saved me a decent amount of setup time.

The hex socket drive seated perfectly on my driver without any wobble, and the zinc plating looks uniform across all 50 pieces. Used them to bolt down a fixture plate and they torqued to spec without a single stripped thread.
