Exact sourced DS8X8 material, length, right-hand four-start 8 mm-lead kinematics, outer/core dimensions, linear mass, and catalog tolerance facts. The solid models the exact thread topology and motion inside the sourced envelope; its rounded tooth is a kinematic representation because igus does not publish the proprietary dryspin flank radii or angles. Full-thread end preparation, coupling grip, support fit, runout, assembled alignment, lubrication-free life, torque capacity, and Belfry suitability remain physically unvalidated.
