براغي رأس مقبس M10-1.25 × 65 مم | محرك مقبس سداسي | خيط جزئي | فولاذ سبائكي فئة 12.9 أسود حراري (50 / عبوة)

The black oxide finish is honestly what sold me—it looks great on the jig I built for my drill press and the 12.9 alloy steel feels rock solid when torqued down. These arrived uniform and threaded cleanly right out of the pack. For the price, fifty of these in a box is a proper deal.

I needed a strong, precise fastener for a jig I was building, and these M10 socket cap screws threaded in perfectly without any binding. The 12.9 alloy steel gives them a solid, industrial feel that I trust for heavy use.

The black oxide finish held up perfectly when tightening these 12.9 alloy steel screws into a precision assembly. They threaded smoothly into the tapped holes with no binding.
