M20-2.5 X 280mm براغي رأس سداسي | فولاذ فئة 8.8 مطلي بالزنك | خيط جزئي (5 / عبوة)

Used these to secure a heavy press at work, and the 280mm length was perfect for getting through the flanges. The zinc plating seems solid so far, no rust after a couple of weeks in a damp shop.

The hex head grabbed my 24mm socket without any wobble, and the zinc coating looks clean and uniform across all five. Threads ran smooth into my equipment frame, though I did have to chase the holes first.

The partially threaded section grabbed just enough for a solid hold, and the zinc coating looks uniform across all five. Wrenched them down with a socket without any stripping or binding.
