براغي رأس مقبس M6-1 × 115 مم | محرك سداسي | خيط جزئي | فولاذ سبائكي من الفئة 12.9 مطلي بالزنك (100 / عبوة)

Installed these on a custom jig I’ve been building, and the 12.9 alloy steel feels noticeably stiffer than the cheaper screws I used before. The partial threading made alignment in tight spots much easier.

The hex socket drive seated the Allen key perfectly with zero wobble, and the 12.9 alloy steel feels rock-solid under torque. These 115mm lengths are exactly what my precision assembly needed, and the zinc plating looks clean and even across all 100 pieces.

These 115mm length screws were exactly what I needed for a custom jig I'm building, and the hex socket drive made installation quick with my Allen key set. The Class 12.9 rating gives me confidence they'll hold up under load.
