T8 Lead Screw 1000mm with Brass Nut – 8mm Diameter 2mm Lead 2mm Pitch Linear Motion Threaded Rod for CNC & 3D Printer in Pakistan

Overview 

The T8x2 1000mm Lead Screw is a premium stainless steel threaded rod engineered specifically for linear motion applications requiring absolute precision and heavy load handling. Unlike standard fastening screws, it features precision-machined Acme-style trapezoidal threads that reduce friction, minimize backlash, and translate rotational force into ultra-smooth linear travel. This 1000mm (1 meter) length is perfect for tall Z-axis builds or long-travel CNC gantries.

Understanding T8x2 (Pitch vs. Lead) 

• Diameter: 8mm (T8).

• Pitch (2mm): The linear distance between two adjacent thread ridges.

• Lead (2mm): The linear distance the nut travels with one single 360^\circ rotation of the screw. Because this is a Single-Start thread, the pitch equals the lead, giving the stepper motor massive rotational leverage and preventing back-driving (Z-wobble or axis dropping).

Key Features

• Self-Locking Design: The 2mm lead ensures the assembly holds its position securely when power to the stepper motor is turned off—no more heavy extruder carriages sliding down automatically.

• High-Grade Stainless Steel: Built to resist bending, wear, and rust, ensuring long-term linear accuracy across its full 1-meter span.

• Matching Brass Nut Included: Shipped with a precision-machined copper/brass nut that exhibits excellent wear resistance and low friction against the steel shaft.

• Smooth Backlash Reduction: Highly consistent thread pitch minimizes positioning errors during fine micro-stepping adjustments.
