M20-2,5 x 80 mm zeskantboutschroeven | Klasse 10.9 staal blank | Gedeeltelijk schroefdraad (20 / verpakking)

Had to use a breaker bar to get these torqued down, but the class 10.9 steel held up perfectly without any stripping. The partial thread gave just enough grip for my equipment mount—definitely buying another pack for future projects.

Perfect spacing on the threads made these M20s easy to start by hand even in tight spots. The Class 10.9 rating gives me confidence they'll hold up under heavy vibration, and the partial threading was just what I needed for a frame repair.

Used these on a heavy equipment jig at the shop and the 10.9 grade steel held up perfectly under torque. The hex head seated cleanly with a standard socket wrench and the partial threading made alignment a lot easier. Solid fasteners for the price.
