براغي رأس مقبس M16-1.5 X 80mm | محرك سداسي المقبس | ملولبة جزئيًا | فئة 12.9 فولاد سبائك مطلي بالزنك (25 / عبوة)

The 80mm length gave me just enough grip for a tricky jig setup, and the zinc plating has a clean, even finish that wiped off easily. All 25 pieces came threaded smoothly with no burrs, which saved me from chasing taps.

The hex socket drive made installation a breeze on my press tooling setup. These 80mm screws have a solid, precise feel when torquing down, and the partial threading is perfect for clamping depth. Exactly what I needed for heavy-duty jig work.

The zinc plating looks clean and even, and the 12.9 alloy steel feels solid in hand—no burrs on the threads, which I appreciate. These are holding up well on my tooling setup so far, and the partial threading gives just enough grip without fighting the shoulder.
