TR 20x4 LH CQA Steel Trapezoidal Leadscrew Nut - Square
CQA Trapezoidal nuts are used as a fastening nut or for manual movement where load is negligible because a steel-to-steel coupling used for movement under load tends to seize. The material used can be MIG welded only. Electrode welding is not recommended because of the lead.
