Anti-Backlash Nut Block for 8mm ACME Lead Screw

From the shop's description

Do want high precision linear motion with a backlash free system for your 3D Printer or CNC Machine? This delrin ACME Anti-Backlash Nut is the ideal choice. With a normal ACME nut block, there will always be some play between the thread of the ACME lead screw and the thread of the nut. With this anti-backlash nut is designed such that the set screw tightens it against the thread, removing any play. Note ACME (tarapazoidal) here means the type of the thread of the lead screw on which we mount the moving nut block. Specifications Pitch: 2mm Lead: 8mm Material: Delrin Thread Type: ACME (Tarapazoidal) 8mm ACME nut block detailed dimensions drawings.
