Color threaded insets

Colored on the surface of stainless steel, mainly for the convenience of the operator can clearly and quickly distinguish between the varieties and specifications of the wire thread. After the color screw sleeve is installed, it is markedly different from the basic color of the die-cast aluminum part (white metal color).This will help to check whether the installation depth of the screw sleeve is suitable and whether it is missing. At the same time, it facilitates the visual management of the warehouse. We have the technology of the domestic patent.
