براغي رأس أسطواني M24-3 × 110 مم | محرك سداسي داخلي | ملولبة جزئيًا | فئة 12.9 فولاذ سبائكي مطلي بالزنك (10/عبوة)

These bolts are seriously beefy. The hex socket drive seated perfectly without stripping, and the 12.9 alloy steel feels rock-solid for our jig assembly; the partial threading gave us just the right grip length.

The zinc plating looks clean and even across all ten screws, and the partially threaded length gave me just the right grip for a heavy jig I’m building. These feel rock-solid for class 12.9, no wobble or softness when I torqued them down.

The hex socket drive seated perfectly on my driver without any wobble, and the zinc plating gives them a clean, uniform finish. Used a few in a jig build and they torqued down solid without stripping.
