M36-4 X 280mm Zeskantbouten | Klasse 8.8 Staal blank | Gedeeltelijk schroefdraad (2 st./verpakking)

The hex heads fit my socket perfectly and the partial threads grabbed cleanly into the frame. No stripped edges, even torquing them down with an impact wrench.

Used these to secure a large jig on the mill table, and the 280mm length gave me just enough thread engagement for the heavy flange. The hex head is beefy enough that a standard socket didn’t slip once, though I’d have liked a finer thread for finer adjustment. Solid buy if you need serious holding

These bolts fit perfectly into the coupling on my hydraulic press, and the 8.8 steel grade gives me confidence they won't strip under heavy load. The partial threading made alignment much easier than fully threaded alternatives I've used in the past.
