براغي رأس أسطوانية M5-0.8 × 65 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 بأكسيد أسود حراري (200/عبوة)

Installed these in a custom fixture and the 65mm length was perfect for reaching through stacked plates. The black oxide finish gives them a clean look and seems to resist minor scuffs from assembly tools.

I needed longer screws for a jig I was building and these 65mm ones were exactly right. The black oxide finish feels durable and the threads are clean, so they seated smoothly.

The hex socket drive on these M5 screws gives a secure grip without stripping, even in tight spaces. The partially threaded shaft makes alignment in jigs much faster than standard bolts. Solid feel for precision work.
