براغي رأس أسطوانية M8-1.25 × 25 مم | محرك سداسي داخلي | ملولبة بالكامل | فئة 12.9 سبائك فولاذية مطلية بالزنك (200 / عبوة)

Installed these on a jig I'm building and the 12.9 alloy steel feels noticeably tougher than standard hardware. The zinc plating has a clean, even finish, and the fully threaded shaft gave a solid grip without cross-threading.

Used a handful to secure a heavy steel bracket for a home workbench and the hex socket held up perfectly under torque without any stripping. The zinc plating looks clean and consistent across all 200 pieces, which is exactly what I needed for a long-term project.

The threads were perfectly clean and the hex socket drive seated the wrench snugly right out of the box, which made quick work of my jig build. The 12.9 alloy steel feels seriously tough for the price, and the zinc plating has a consistent, even finish across all 200 pieces.
