براغي رأس مقبس M6-1 X 100mm | رأس مسطح بمحرك مقبس سداسي | ملولبة جزئياً | فئة 12.9 فولاذ سبائكي مطلي بالزنك (100 / عبوة)

The hex socket drive seated perfectly on my Allen key, and the 100mm length gave me just enough grip for the jig I was clamping down. Threads ran smooth through the tapped holes without any binding, and the class 12.9 hardness feels reassuringly solid for the tooling work I'm doing.

The zinc plating looks uniform across all 100 pieces, and the hex socket drive seated cleanly without stripping on my torque wrench. Class 12.9 alloy steel feels proper for a fixture I'm building. Shipping was fast, too.

The hex socket drive made tightening these into my tooling setup effortless, and the zinc plating feels durable enough for repeated use. Definitely a solid choice for precision assemblies.
