براغي رأس مقبس M6-1 × 90 مم | محرك سداسي | ملولبة جزئيًا | فئة 8.8 من سبائك الصلب مطلية بالزنك (200 / عبوة)

I needed partially threaded bolts for a custom jig, and these M6-1 x 90mm screws seated perfectly with a hex key. The zinc coating looks uniform and should resist rust in my shop.

The 90mm length was exactly what I needed for a deep clamping fixture, and the hex socket drive made tightening them in tight spots effortless. They threaded smoothly into tapped holes without any binding, and the zinc plating looks clean and consistent across all 200 pieces.

Installed these on a jig I’m building, and the partially threaded design made alignment much easier. The zinc plating looks clean and seems like it’ll hold up well.
