براغي رأس أسطواني M10-1.5 × 120 مم | رأس مسطحة محرك سداسي | خيط جزئي | فولاذ سبائكي فئة 12.9 مطلي بالزنك (50/عبوة)

I work on heavy machinery and these M10x120 partially threaded screws are exactly the right length for bolting down motor mounts. The hex socket drives made installation quick, even in tight spots. All 50 were cleanly threaded and the zinc finish looks uniform.

Used a full box to build a custom jig for work, and every single screw seated perfectly with no galling. The hex socket drive bit fit nice and snug, so no stripped heads on the tighter spots. These 12.9-grade alloy screws really hold up under heavy clamping loads.

The partial threading on these screws made lining them up in my tooling fixture much easier than I expected. They hold tight with a satisfying feel when torqued down, and the zinc coating looks clean and durable.
