ABSTRACT:
A lead screw is coated with Teflon to protect the screw from a high humidity atmosphere and to eliminate the need for lubricants which would tend to collect corrosion products and form a grinding compound. A nylon nut is used in combination with the Teflon coated screw since the nylon deforms to load all of the threads whereby the Teflon coating is not peeled off.
