M20-2,5 X 280mm Zeskantkopschroeven | Staal klasse 10.9 blank | Gedeeltelijk schroefdraad (3 / Verpakking)

The partially threaded design made them perfect for my jig fixture where I needed a smooth shank section for clearance. The hex heads seated cleanly with a socket wrench, and the 10.9 steel feels noticeably tougher than the standard bolts I was using before.

Used these on a conveyor belt repair where standard bolts were too short. The 10.9 grade held up well under heavy load, and the partial threading made installation easier. No complaints after a week of continuous use.

I needed a longer bolt for a heavy equipment repair and these 280mm cap screws fit the bill perfectly, the threads engaged smoothly. The hex head made torquing them down easy with a socket, and the class 10.9 steel feels solid enough for the job.
