براغي ذات رأس أسطواني مجوف M8-1.25 × 140 مم | محرك سداسي مجوف | خيط جزئي | فولاذ سبائكي من الفئة 12.9 مطلي بالزنك (50 قطعة/عبوة)

I needed these for a jig I was building, and the 12.9 grade alloy steel feels way tougher than standard bolts—definitely holding up under heavy use. The partially threaded shaft gave me just the right grip length for my assembly.

The partially threaded design made aligning them into a jig much easier than expected. These screws feel rock-solid and the zinc plating looks clean.

Needed a full set of heavy-duty socket cap screws for a press jig, and these M8-1.25 x 140mm held perfectly under clamping load. The zinc plating looks clean and uniform, no rough edges or burrs. 50 pieces in the pack is a solid deal for shop use.
