براغي رأس كبس M12-1.25 × 65 مم | محرك سداسي | خيط جزئي | فئة 12.9 سبيكة فولاذ مطلي بالزنك (50 / عبوة)

I've been using these in a few jig builds and the hex socket drive seats really securely with no stripping. The 12.9 alloy steel feels much tougher than the standard grade 8 bolts I'd grabbed before.

The hex socket drive gripped perfectly on the first try, no slipping or rounding, even when I torqued them down on a jig fixture. The 65mm length with partial threading gave just the right bite for my assembly, and the zinc plating on all 50 looked uniform and durable.

The threading is clean and the zinc coating looks uniform across all fifty, so no rust worries yet. Used them to bolt down a steel base plate and the 12.9 hardness really shows when torquing them tight.
