براغي رأس أسطوانية M24-3 × 200 مم | محرك سداسي | ملولبة جزئيًا | فئة 8.8 سبائك فولاذ مؤكسد أسود حراريًا (10/عبوة)

The black oxide finish on these is a nice touch—slick and uniform, no flaking when I torqued them down. Threads engaged cleanly on the first pass, and the class 8.8 steel feels solid for the tooling fixture I put together. I’ve got ten spares now, which is exactly what I needed for the next job.

The partially threaded length is exactly what I needed for my jig build—the threads grab cleanly while the smooth shank lines everything up perfectly. The hex socket drive made torquing them down in tight spots a breeze, and the black oxide finish looks properly done.

These things are solid—the black oxide finish is holding up perfectly on my assembly fixture after a full week of use. Drive engagement with the hex socket is clean and tight every time.
