براغي رأس سداسية M8-1.25 × 45 مم | فولاذ فئة 10.9 عادي | خيط جزئي (200 / عبوة)

Used a whole bag on a heavy-duty shelving project and every single one seated perfectly in the hex driver without stripping. The 45mm length gave just enough thread engagement for the steel beams without bottoming out.

Finally, a hex head screw that doesn't round off under high torque; the Class 10.9 steel feels incredibly solid. Used a dozen so far in a jig assembly and each one seated perfectly without any binding.

The 45mm length was perfect for securing a heavy motor mount on a steel frame. I used a torque wrench to hit the spec and not a single one stripped or felt soft during tightening.
