M8-1,25 x 170 mm Sechskantschrauben | 18/8 Edelstahl | Teilgewinde (25 Stk./Packung)

Popped one of these in with a socket wrench to hold a jig together, and the hex head grabbed perfectly without any slipping. The 18/8 stainless finish looks clean and feels solid against the steel frame, no rust worries so far.

The partial threading on these 170mm cap screws made alignment much easier when I was bolting through a thick steel bracket into a tapped hole. The stainless finish looks clean and hasn't shown any corrosion after a few weeks in a damp shop.

Had to order these for a custom jig build, and the 170mm length paired with the partial threading let me get plenty of grip without bottoming out in my aluminum frame. The stainless steel finish hasn't shown any rust even after a few weeks in a damp shop.
