براغي رأس مقبس HOLO-KROME 87149 M10-1.5 X 16mm | رأس مسطح بمحرك سداسي داخلي | فولاذ سبائكي مؤكسد أسود حراريًا (100 / عبوة)

I needed these for a fixture build and the 16mm length was exactly what I was looking for. The black oxide finish held up well during assembly without any galling.

Used these M10 socket cap screws for a jig I was building and the black oxide finish held up great under the clamp pressure. The hex drive seated perfectly without any stripping, even when torqued down. Exactly what I needed for precision assembly work.

I needed a solid batch for some jig repairs, and the black oxide coating on these screws seems evenly applied with no flaking. They threaded cleanly into pre-tapped holes, though I wish the package had a few extra spares for the price. Overall a reliable set for small machinery fixes.
