Finally, a batch of socket cap screws where every single one has clean, sharp hex drive slots; the Class 12.9 rating gives me real confidence for the jig fixtures I'm building.

The hex drive on these 40mm screws grabbed my Allen key perfectly, no stripping at all. They feel solid for jig building, and the partial threading made installation quick.

Finally got these M5 socket cap screws for my jig setup, and the hex socket drive made installation a breeze with no stripping. The 12.9 alloy steel feels incredibly tough, and the zinc plating gives them a nice, even finish. Exactly what I needed for precision work.
