Professional Applications & Engineering Value
This M20x4 mm Metric Trapezoidal Lead Screw is engineered to solve critical challenges in precision motion control systems. The carbon steel material, treated with a black oxide finish, combats corrosion while maintaining the Rockwell B72 hardness needed to withstand repetitive mechanical stress. Its single-start, right-hand thread with a 4 mm pitch delivers consistent 4 mm axial movement per revolution, minimizing positional errors in CNC machinery, linear actuators, and automated positioning tables. The fully threaded 2000 mm design supports long-travel applications, eliminating the need for splicing in conveyor systems or Z-axis drives. By adhering to ASTM A108 standards, it ensures interoperability with metric trapezoidal nuts, reducing assembly time and maintenance costs in industrial automation and packaging equipment.
Specification Summary & Compliance
This lead screw features an M20 thread size with a 4 mm pitch and 7e thread fit per ISO metric trapezoidal standards, ensuring precise Class 2A equivalent tolerances for smooth operation. It is manufactured from Grade 2 carbon steel under ASTM A108 material specifications, and is fully RoHS 3 (2015/863/EU) compliant, meeting international environmental directives for hazardous substance restrictions.
