M12×12mm 平端內六角止付螺絲 | 合金鋼 (250個/包)

The flat point tip on these set screws held perfectly against the shaft without marring the surface, and the hex drive let me get them torqued down in a cramped spot. Exactly what I needed for a stubborn alignment job.

The hex socket drive made tightening these in a tight spot a breeze, and the flat point held perfectly on the shaft. For the price, getting 250 pieces of alloy steel is a solid deal.

I needed a set screw that wouldn't strip under heavy torque, and the hex socket drive on these handles that perfectly in tight spots. The flat point grips the shaft firmly without marring it, and the alloy steel feels tough enough for repeated adjustments. Really solid value for a bulk pack.
