براغي رأس مقبس M10-1.5 × 55 مم | محرك سداسي المقبس | ملولب جزئيًا | فولاذ سبائكي درجة 12.9 مجلفن (50 / عبوة)

Packed a full 50-count box with no missing or damaged threads, and the 12.9 alloy steel feels seriously robust. The zinc plating is even and smooth, and the partial thread gave me perfect grip on my tooling fixture.

The hex drive on these 55mm socket screws fits my wrench perfectly, no slippage at all. Used them for securing a jig in my workshop and they held tight with zero issues. Solid 12.9 alloy steel feels durable enough for years of use.

The partial threading on these M10-1.5 x 55mm screws made aligning them in my jig much easier than fully threaded ones. The hex socket drive let me torque them down precisely without stripping. Fifty in a pack for that price feels like a solid value.
