براغي رأس أسطوانية M20-2.5 × 60 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 8.8 مطلي بالزنك (25 / عبوة)

I needed a batch of heavy-duty fasteners for a jig I was building, and these M20 screws have the exact thread pitch and hardness I was after. The zinc plating seems consistent and hasn't chipped during installation.

These fit perfectly into my drill press jig, and the zinc plating has held up well against oil and chips. The hex drive made installation quick with no stripped sockets.

I've used these to build a couple of jigs in the shop, and the fully threaded length meant I could cut them to exact size without wasting a single one. The class 8.8 alloy steel feels plenty rigid for the torque I've applied, and the hex socket drove cleanly without stripping.
