براغي رأس أسطواني M24-3 × 200 مم | رأس مسطح محرك سداسي داخلي | ملولبة جزئيًا | فولاذ سبائكي فئة 10.9 أكسيد أسود حراري (5/عبوة)

The black oxide finish on these screws looks great and seems like it will resist rust well in my shop jigs. The hex socket drive made installation straightforward with no stripping.

I needed a bolt that could handle heavy jig loads without stripping, and the hex socket drive on these 200mm screws gives me a solid, reliable bite. The black oxide finish feels durable and hasn't shown any wear after a few weeks of assembly work.

The threads on these M24s cut cleanly into my jig plate without any binding, and the black oxide finish feels properly done—no flaking after a day of clamping. Partially threaded length is just right for the 200mm reach I needed.
