M20×50mm 平端內六角止付螺絲 | 合金鋼 (25顆/包)

Installing these M20 set screws was a breeze thanks to the flat point tip, which gripped the shaft perfectly without any slipping. The alloy steel feels robust and the hex socket drive handled my torque wrench without stripping. Exactly what I needed for a heavy-duty fixture adjustment.

The hex socket drive made torquing these into a tight spot surprisingly easy—no stripped heads or fumbling. The flat point seated firmly on the shaft, and the alloy steel feels solidly machined for the price. Exactly what I wanted for a heavy adjustment job.

The hex socket drive let me really torque these down in a tight spot without stripping the head. With 25 in the pack, I've got plenty left for future projects, and the alloy steel feels solid enough for heavy use.
