The assembly includes a sleeve 10 and a toggle 12 with an inner diameter corresponding to an outer diameter of the sleeve. The toggle is made of an aluminium alloy. Surfaces of the toggle have a protection film of different colours formed by an anodic process. The protection of the toggle prevents the surfaces from cracking, collision, mist or from falling off. Alternatively the toggle may be made of iron with a surface electroplated with a copper bottom layer. An anodic process is used to enable an indication of sizes 13, for example socket sizes, to be made. The toggle and sleeve may be printed with the size of the sleeve by laser printing. Surfaces of the toggle and the sleeve may be machined with textures or patterns. The sleeve may include an annular recess for rotatably receiving the toggle. The toggle 12 may be an annular ring or a C ring. |
