براغي رأس كبس M4-0.7 × 110 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 مطلي بالزنك (50/عبوة)

Zinc plating looks clean and even across all fifty, no scratches or bare spots. The hex socket seated perfectly on my driver and the 12.9 alloy steel feels reassuringly solid for the jig I'm building. Turned them in without a single stripped head.

I use these in jig assembly where I need a clean, flush finish with a hex key, and the zinc plating has held up well without rust through daily adjustments. The partially threaded design lets me grip tightly without bottoming out, which saves me from tapping deeper holes. They're tougher than cheape

The 110mm length on these M4 screws is exactly what I needed for a custom jig setup. They threaded smoothly into my aluminum fixture plate without any binding.
