These three attributes are important because the combination of any of them, in addition to the screw diameter, will impact the load capacity and efficiency of the lead screw.
Great explaination. I asked Chat GPT what was a lead screw and got me confused with the concept of pitch. Then I asked again what was the difference between pitch and lead . I admit I thought pitch was the traveled linear distance per one rotation regardless of the numbers of starts... I learnt something quite important today, especially with this video since it explain it better that ChatGPT. Thanks a million!
