Selection and use

The square-form housing distinguishes this spring-loaded anti-backlash nut from the other brass spring nut style; check the mounting shape carefully. A Tr8x4 nut must be paired with a screw of the same nominal diameter, pitch, and lead: the different T8 leads are not interchangeable. Check the physical mounting shape, hole positions and clearance against your existing assembly before ordering; those dimensions are not confirmed here.
