The Tr8x4 spring-loaded anti-backlash brass nut is designed for a nominal 8 mm diameter trapezoidal-style lead screw with a 2 mm pitch and 4 mm lead. With 2 thread starts, a matching screw provides 4 mm nominal travel per revolution. This screw family is also commonly listed as T8x4.

Selection and use

The spring-loaded anti-backlash arrangement is intended to reduce axial free play in a matching screw-and-nut assembly. 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.
