براغي رأس مقبس M5-0.8 × 160 مم | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ سبيكة فئة 12.9 مطلي بالزنك (25/عبوة)

These 12.9 alloy steel bolts are seriously tough—I used them to secure a guide rail on a milling fixture and they didn't budge under heavy load. The zinc plating looks clean and resists rust so far. Exactly what I needed for precision tooling work.

I needed a longer bolt for a custom jig I was building, and the 160mm reach on these M5 screws gave me exactly the clearance I required. The hex socket drive was crisp and didn’t strip when I torqued them into steel.

The 160mm length was perfect for a deep assembly I was working on, and the hex drive seated firmly without stripping. The zinc plating looks clean and uniform on all 25 pieces.
