براغي M16-2 X 100mm برأس مقبس | رأس مسطح بمحرك مقبس سداسي | ملولبة جزئيًا | فئة 10.9 من سبائك الصلب بطبقة أكسيد أسود حراري (25 / عبوة)

Needed some robust fasteners for a heavy jig build, and the partially threaded design on these M16s made alignment much easier. The black oxide finish slides into place smoothly and looks clean against the steel.

Used these on a precision milling fixture and the partially threaded design made alignment much easier during setup. The black oxide finish has a nice non-glare look and seems durable so far. Fit was spot-on and no stripping during installation.

Installed these on a custom jig for repetitive clamping, and the flat head sits perfectly flush every time. The thermal black oxide finish held up well against light oil and debris during the first week of use.
