This bar is usually used to connect the strap of a handbag to the bag itself but because they are threaded, they sometimes come loose and need replacing.
If you are that unlucky person who has lost one of these and you think this may do the job as a replacement then I would advise you to use thread lock on the end to avoid losing this one.
To help you decide if this is correct please see the dimensions below:
Head Size: 12mm
