Customer Reviews (4.8 / 5 · 5 reviews)

Harper J. ★★★★★

The zinc plating held up nicely during installation without any flaking, which was my main worry with cheaper sets. I used these to lock down a pulley hub and the cup point bit into the shaft exactly as intended. Worth the money for the full box.

Christopher ★★★★★

The cup point tip seated perfectly flush against the metal surface, giving a clean, professional look. These feel solid and durable, and the zinc coating seems like it’ll resist rust well. Exactly what I needed for a heavy-duty fastening job.

Robert R. ★★★★★

The hex socket drive made tightening these into a tight motor mount bracket surprisingly easy, and the cup point bit into the shaft without slipping. Finished the job in half the time I expected.
