6mm X 25mm 內六角螺絲

Used these to mount a bracket onto my workbench and the hex drive seated perfectly without stripping. The 25mm length was just enough to get a solid hold through the frame.

The threads engaged smoothly and the hex socket was cleanly machined. Used these to secure a bracket on my lawnmower deck and they haven't budged. Solid little fasteners for the price.

The threads are clean and consistent, so these cap screws fit perfectly into pre-tapped holes without binding. They feel sturdy enough for light-duty replacement work, though I wish the pack had a couple more spares for the same price.
