براغي رأس مقبس M10-1.5 × 35mm | محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبيكة كلاس 12.9 مطلي بالزنك (100/عبوة)

Zinc plating looks even and the hex socket drive seats the Allen key cleanly without any wobble. Threads ran smooth into my jig plate, and the 12.9 hardness gives me confidence they’ll hold torque on the tooling.

Pulled these out of the pack and immediately noticed the consistent threading and solid zinc coating — no burrs or rough edges. They torqued down perfectly into my precision assembly without any stripping. Exactly what I needed for a dependable build.

Installed these in a jig I’m building and the 12.9 alloy steel feels noticeably tougher than the standard screws I’ve used before. The zinc plating looks clean and should resist rust in my shop environment.
