براغي ذات رأس مسطحة ومقبس سداسي M10-1.5 X 65 مم | بخيوط جزئية | فولاذ سبائكي فئة 12.9 مطلي بالزنك (100 / عبوة)

I’ve used a dozen of these in a jig I built, and the 12.9 alloy steel holds up way better than the usual hardware-store stuff. The hex drive seated firmly with no stripping, and the partial threads made alignment a breeze.

These bolts are the right specs for my press tool rebuild, and the zinc plating looks clean and consistent across all 100 pieces. The hex socket drive bit seated firmly without any wobble, which I appreciated during assembly.

Threaded perfectly into my jig fixture without any binding, and the zinc plating looks clean and consistent across all 100 pieces. For the price, getting Class 12.9 strength in a partially threaded design is exactly what I needed for heavy-duty tooling.
