Product benefits Smooth, consistent linear motion: T8 screw thread with a clear, complete profile delivers even force distribution and smooth sliding for reliable actuation. Full-length engagement: 400 mm full-thread rod provides full travel engagement along its length for consistent performance over the entire stroke. Durable materials: Brass nut and corrosion-resistant components reduce wear and rust for a longer service life in typical workshop and industrial environments. Versatile configuration: 15-in-1 400 mm full-thread rod T8 screw with brass nut offers flexibility for a range of mechanical assemblies and retrofit projects. Key features Function: Precision lead screw for converting rotary motion to linear motion with steady, predictable force. Compatibility: Designed for use with common motion systems in printers, CNC machines, automatic machines, and molding machines. Size and model: T8 profile, 400 mm full-thread length, supplied with brass nut. Performance: Clear thread form and full engagement reduce binding and uneven load, improving repeatability and smoothness. Practical use scenarios 3D printer Z-axis: Replace or upgrade the Z-axis lead screw to improve layer-to-layer consistency and reduce step artifacts caused by uneven movement. CNC and routing systems: Use as a feed screw for small CNC routers or positioning stages where smooth, repeatable linear travel is required. Automated equipment and molds: Integrate into linear actuators or positioning mechanisms in automated assembly or molding machines to provide reliable motion and corrosion-resistant operation. What this solves Prevents jerky or uneven motion caused by incomplete or worn threads. Reduces maintenance frequency thanks to corrosion resistance and a durable brass nut. Provides a straightforward, compatible option for common machines that require a T8 full-thread lead screw. Technical summary Type: T8 screw thread Length: 400 mm full-thread rod Nut: Brass nut included Configuration: 15-in-1 400 mm full-thread rod T8 screw with brass nut Applications: Printers, CNC machines, automatic machines, molding machines
