The hex socket drive grips the Allen key cleanly, no stripping even when I torqued them down tight. These steel screws held a pulley dead-straight on the shaft through a full day of heavy use, and the 50-pack means I've got spares for the next job. Exactly what I needed.

These little guys bit into the shaft perfectly without stripping, even after I torqued them down hard with a hex key. The steel finish feels solid and they came well-packaged in a 50-count tray. Exactly what I needed to lock down a stubborn pulley.

The hex socket drive made installation straightforward, and the steel construction feels solid enough for locking down a pulley on a motor shaft. Worked perfectly for my application.
