H-Type T8 Lead Screw Nut – 2mm & 8mm Pitch Options

By using this T8 flexible nut with H-type threading, stable and low-friction vertical movement is achieved along the Z-axis lead screw in FDM-style 3D printers. Manufactured from durable POM (polyoxymethylene), the nut resists wear while offering self-lubricating properties ideal for linear motion. The internal flexible mechanism helps absorb minor alignment discrepancies and reduces backlash. Available in 2mm or 8mm pitch variants, this component enables controlled Z-axis elevation for accurate layer placement and reduced mechanical stress during travel.
