براغي رأس مقبس M8-1.25 X 150mm | محرك سداسي | ملولبة جزئيًا | فئة 12.9 من سبائك الصلب مطلية بالزنك (50 / عبوة)

The zinc plating looks clean and even, and the hex socket drive seated perfectly with my Allen key on the first try. These 150mm lengths are exactly what I needed for a jig setup, and the partial threading gives plenty of grip without the threads chewing up the workpiece.

Needed some long fasteners for a milling fixture, and these 150mm ones fit perfectly. The hex socket drive makes installation quick, and the zinc coating looks solid.

For a jig I'm building, the partially threaded design made alignment much easier than fully threaded cap screws. These Class 12.9 bolts feel rock solid and the zinc finish looks clean.
