Abstract
A leadscrew assembly includes a leadscrew having an elongated shaft with an outer lateral surface and a rotational axis, and a leadscrew thread formed of a thread wire helically wrapped in spaced-apart turns upon the lateral surface and affixed to the elongated shaft. A hollow drive nut housing includes a nut bore having an unthreaded inner surface. The leadscrew is inserted through the nut bore. The nut bore is sized such that the leadscrew may rotate therein about the rotational axis. A spring pin is affixed to the drive nut housing and spans across the nut bore to engage the leadscrew thread.
