Product Description

These custom CNC modified-profile cylinder coupling nuts are non-standard metal fasteners manufactured by CNC turning. Different from standard regular nuts, they adopt special customized outer contour with precision-processed internal threads.
All products are produced strictly following customer drawings or sample requirements. Multiple material choices meet different requirements on tensile strength, hardness and corrosion resistance. Thread tolerance is well-controlled to guarantee smooth screwing and stable connection performance.
This series of custom nuts are widely used for mechanical equipment, fixture tooling and other non-standard assembly occasions. We support custom thread size, overall dimension, outer shape and surface finishing. Both small trial batches and large-volume industrial OEM orders are welcome.
