M20-1,5 X 140 mm Zeskantbouten | Klasse 8.8 staal blank | Gedeeltelijk schroefdraad (10 / Verpakking)

Needed a dozen of these to finish a frame jig, and the 140mm length with partial threading gave me just the grip I wanted without bottoming out. The hex heads seated cleanly with a socket wrench, no stripped corners. For the price, these are solid for general assembly work.

Checked the threads against a tap before use and they're cut clean, no burrs or rough spots. The partial thread section gave me just enough grip for the heavy flange I was bolting down, and the 8.8 hardness feels solid under torque.

The partially threaded section grabbed threads fast and the unthreaded shank gave me a solid, precise fit for aligning two steel plates. Class 8.8 is plenty stiff for the machine frame I bolted together, and the hex head sat flush with a standard socket.
