I needed cheap lead screws and they were supplied. The box was packed well enough as all 4 I bought were straight. These bad boys have 4 strands, 2mm spacing, 8mm awesomeness. The nut that came with it is rubbish. The batting is literally impossible to compensate. it said. I'm using some cheap play nuts for the final project and if you plan on using some (you should) these are great screws. At $15 for 2 bolts and $5 for a set of anti-backlash nuts, this is quality precision for $10 per axle. You will have a hard time beating these dollar for dollar.
