براغي رأس كبسولة M12-1.75 × 65 مم | رأس زر بمحرك سداسي | ملولب بالكامل | فولاذ سبائك كلاس 10.9 مطلي بالزنك (50/عبوة)

Installed these on a jig I’m building for a machining project, and the fully threaded length gave me exactly the grip I needed. The zinc finish seems solid, no burrs on the heads.

I was pleasantly surprised how well these held torque when I used them to secure a heavy base plate on my bench vise. The hex drive engagement feels precise and the zinc finish makes them easy to clean up with a rag. Definitely solid enough for 10.9 alloy steel fasteners.

The zinc plating looks clean and even across all 50, and the hex socket drive seated perfectly on my torque wrench without any stripping. Threads ran smooth into the jig plate I machined this week, so they're doing exactly what I needed for precision assembly.
