براغي رأس أسطواني M8-1.25 × 85mm | محرك سداسي برأس مسطح | ملولبة جزئيًا | فئة 12.9 من سبائك الصلب مطلية بالزنك (100 / عبوة)

The threads on these M8s are cut clean and the zinc finish is uniform across all 100 pieces, no duds in the batch. I've been using them for fixture builds and the hex socket engages firmly without any stripping. For 12.9 grade at this price per unit, they're a solid value for shop stock.

The partially threaded design makes them grip securely in my fixture plates without bottoming out, and the zinc coating has held up fine so far. Only wish they came with a few extras in the bag since I always lose one or two.

The flat head seats flush perfectly in my jig setup, and the partial threading gives just the right grip for clamping. I did have to chase a couple of threads with a tap since the zinc plating felt a bit tight, but for 100 pieces at this price, they're a solid buy.
