I needed some precise fasteners for a jig I was building, and these M8s fit perfectly with their clean hex drive. The 22mm length was spot-on for my application, and the black oxide coating looks professional.

The hex socket drive made installation really smooth with my Allen wrench, and the 22mm length was perfect for securing a jig I built. The black oxide finish seems durable so far, and the threads engaged cleanly without any binding. Exactly what I needed for my workshop tooling.

The black oxide finish on these screws is holding up well in my jig setup, no rust after a week in a damp shop. They thread smoothly into my aluminum fixture plates without binding. Exactly the Class 10.9 strength I needed for a decent price.
