M2.5-0.45 X 25mm Socket Cap Screws | Hex Socket Drive | Partially Threaded | Class 12.9 Alloy Steel Zinc Plated (100 / عبوة)

Finally, a fastener that doesn’t strip when torquing down on a jig—the Class 12.9 zinc plating feels tough and the partial threading saved me from a jammed fit. Perfect for precision assemblies.

The hex socket drive grips the Allen key perfectly, no rounding even at snug torque. Threads ran smooth into my precision jig setup, and the 12.9 alloy steel feels tougher than the usual stuff I've used.

The zinc plating on these held up well during assembly, no flaking or galling on the threads. They're just the right length for my jig build, though the partially threaded section meant I had to double-check clearance on one blind hole.
