براغي رأس مقبس M12-1.75 × 45 مم | محرك سداسي | كاملة الخيوط | فولاذ سبائكي من الفئة 8.8 مطلي بالزنك (100 / عبوة)

These bolts threaded smoothly into my machinery jig without any binding, and the zinc plating looks clean and uniform. The hex socket drive gave me a solid grip for torquing them down precisely.

Just got these for some heavy-duty jig builds I'm working on, and the Class 8.8 alloy steel feels solid—the zinc plating's a nice touch for resisting shop grime. They threaded perfectly into pre-tapped holes without any binding, exactly what I needed for 45mm lengths.

I've been using these to rebuild a jig for my press, and the hex socket drive makes seating them deep in tight spots so much easier. All 100 arrived with clean threads and the zinc plating hasn't shown a hint of rust yet after a few weeks in a damp shop. For the price per piece, they're a solid buy
